Field of the Invention The present invention relates generally to methods and systems for determining the presence of a chemical element or compound, and more particularly, to such methods and systems that stimulate substances at selected frequencies of resonance, to produce characteristic patterns of emission that can be detected locally or from a remote distance to determine the identity and location of the substance. 2. Description of the Related Art: A number of patents have been issued that relate to techniques for relatively short-ranged location systems, and most are designed to find a particular class of substances. Typical of these are U.S. Pat. Nos. 5,159,617, and 5,233,200, issuedto King et al., and Buess, et al., respectively. These patents typically relate to substances that contain Nitrogen, and generally use electromagnetic fields to disturb atomic structures, and measure the resulting emissions, as the atoms return tonormal. Compared to the proposed method disclosed herein, these techniques are extremely limited, both in type of substances that can be detected, and in detection distance. Means of stimulating substances artificially are part of the present invention. Also, it has been found, by the present inventors, that substance emitted noise signals require interpretation in order to be useful for substance identification. Means to interpret substance generated noise is also an important part of this invention. SUMMARY OF THE INVENTION It is an object of the present invention to provide a method and system for identifying and locating a targeted substance either locally or remotely. It is another object of the present invention to provide such a method and system that does not destroy or damage the targeted substance. These and other objects of the present invention are met by a remote substance identification and location method and system disclosed herein that uses an ionization means used to ionize an intermediate chemical to produce a probing signal, alsocalled a plasma, used to simulate and sense the response from a desired substance located in a target area. The intermediate chemical can be any chemical that undergoes ionization caused by an IR laser beam source. The embodiment disclosed herein isused in an open area exposed to the atmosphere where the intermediate chemical is oxygen, or nitrogen. During use, the probing stimulating signal is aimed at or in the general direction of a desired target substance causing the target substance toundergo non-destructive molecular resonance to produce a characteristic electrical response field. The electrical response signal is then detected by IR detectors tuned to the same electromagnetic band as the intermediate chemical. The IR detectors areconnected to a preamp and an analog/digital converter which interfaces with a computer. Loaded into the memory of the computer is a software program that is programmed with a library of electrical response signals from known target substances using acalibration method a first algorithm. The software program includes a second algorithm that compares the received electrical response signals to electrical response signals from known substances to determine the identity and location of the targetsubstance. In the preferred embodiment, the intermediate chemical is oxygen which is ionized by the IR laser beam source to create a single pulse-modulated plasma that causes molecular resonance in the target substance. In one embodiment, the ionization means is an optical radiation source, such as an IR laser beam source. In another embodiment, the ionization means is a voltage radiation source, such as an antenna.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S) Disclosed herein and depicted in the accompanying FIGS. is a remote substance identification and location method and system 10 also referred to as Object Location by Electrical Response (OLER). The method, depicted generally in FIG. 1, includesa first step of creating a probing signal by ionizing an intermediate substance, propagating the probing signal to the area containing a target substance 70 which creates an electrical response field from the target substance, detecting the electricalresponse field from the target substance 70, and then analyzing the electrical response field to identify, and locate the target substance 70. FIG. 2 depicts an overall summary of the system 10 while FIGS. 3-5 depict three specific design applicationsof the system. FIGS. 6-9 are illustrations and schematic diagrams showing two types of plasma generators used in the system 10 while FIGS. 10 and 11 are flow diagrams of two software algorithms used by the system 10. Remote identification and location of arbitrary molecular substances has long been a goal of many inventors, but has generally gone unfulfilled. Standard substance identification methods include laboratory techniques, such as Nuclear MagneticResonance, and Optical Spectrometry, but these methods provide no means of identifying substances in field conditions, except in astronomy, nor do they have distant location capability. The technique known as X-Ray Fluorescence (XRF) is being used infield work to find and measure certain substances, but the maximum range of XRF operation is a few inches, so it is not capable of remote monitoring, and is severely limited by range in locating objects. Other techniques that have been used include,x-ray, and acoustic means to measure density of a substance, and means of measuring earth conductivity anomalies, for buried objects. Probably the best method to date for locating certain substances is the animal sense of smell, but this method isobviously limited to substances that provide a smell. The advantages of the system 10 disclosed herein over other systems found in the prior art is the ability to locate small or large amounts of target substances at different distances While some substances, of course, are stronger signal sourcesthan others, the system 10 may be adjusted to identify and locate a wide variety of different target substances. For example, gasoline is considered a relatively strong target source, and a tank of gasoline in an automobile can be detected a city blockaway. A tank-farm of gasoline can be detected more than 3 miles away. The system 10 also offers a method of finding people buried in avalanches, and rubble, even finding dead bodies, and could be used in police searches for weapons, bombs, and narcotics. It could be used in mining to locate precious metals, andgems, though the technique may not penetrate deeply into the soil, and tests of soil penetration have not yet been made. The potential list of uses is long. Obvious important uses of the system 10 include means to alert security persons to presence ofplastic explosives that are extremely difficult to detect by other means. Another advantage of the system 10 is its inherent safety. Detection methods do not require hazardous materials, such as nuclear sources, or other dangerous radiation. The electromagnetic radiation associated with the system 10 is hardly morethan a person experiences when walking across a carpet, and much less than one gets standing in sunlight. Stimulation of a Target Substance It is postulated that most, if not all, substances generate characteristic electrical response signals when stimulated with a "proper" electrical signal. These response signals, are low in frequency, and are electrically weak, which is to saythat their source impedance is extremely high even though their voltage levels may be moderate to high. Actual values are difficult to measure, and are not yet known, because an adequate model has not been built. Response signals have been found in the frequency band from nearly DC to approximately 200 MHz. It is anticipated that that frequency may be a limitation of the present instrumentation, rather than of the substances, or the propagation medium. The system 10 uses a probing signal to simulate and sense a response from a desired substance located in a target area. The probing signal is produced by an ionization means that ionizes an intermediate chemical that is propagate, stimulate, andsense the target area. In the preferred embodiment, the intermediate chemical undergoes ionization caused by an IR laser beam source. It is postulated that the probing signal causes the resonance in the electron clouds in the molecules of theintermediate substance. It is accepted that all substances consist of combinations of atoms held together with shared electrons, commonly called valence electrons. In his book, The Nature of the Chemical Bond, Linus Pauling, explored the wave-likenature of electrons, and showed how, in chemical bonds, electrons form a stable waveform when considered as a mutual resonance of two waveforms. Now, electrons are charged particles, so it follows that they can be moved (attracted, or repelled) byelectric fields, and if the frequency of an alternating E field is adjusted, suitably, the resonant chemical bond will vibrate and eventually break causing an electron to be ejected, like a stone from a sling. The `Q` of the resonance is unknown, but itlikely is quite large, because a very small amount of energy, added over a relatively long time period, can create the effect. Moreover, resonances can be stimulated using one of many sub-harmonics. So, it follows that extremely low frequencies can beused to stimulate substances. Characteristic substance stimulation frequencies have been observed to be relatively stable over time, as compared to response signal signatures (see section on Detection). Natural electrical noise can also stimulate these emissions, particularly on sunny days. The system-like signatures found in many substances may be observed during daytime hours without artificial stimulation. It has also been observed thatsome substances can be stimulated at, or near, harmonics of 60 Hz, when located near power lines. Propagation In the preferred embodiment disclosed herein, the propagation of the probing signal and the electrical response signal from the target substance takes place in air with a return current path through the earth, but not necessarily. Wherein, dueto natural presence of air atoms with orbital electrons, and ions, electrical response signals generated at one location can be transmitted through the ion/air "fluid" by physical shift, or vibration, of electrons, or ion particles, as described inplasma physics. This effect is similar to well known principles of acoustics, substituting electric field force for mechanical pressure. Like acoustics, the propagation medium is subject to ducting, that is, the formation of low-loss paths, such as thepropagation of sound across a lake. Lonngren, author of "Introduction to Physical Elements", generally describes ion acoustic waves having properties similar to those observed by the inventors, and it is expected that this propagation mode is a plasmaphysics phenomenon, perhaps like the Ion Acoustic Wave, but using the vibration of orbital electrons of air molecules, because light electrons would provide a higher propagation velocity, and response frequency than would heavier ions. Unlike ordinary acoustics, the ions that provide the propagation are physically moved to generate plasma paths. This may be accomplished by either of two methods: 1. application of light at emission wavelengths of Oxygen (e.g. 820 nm), aspublished in the Handbook of Chemistry and Physics. Or, a simple grounded sharp pointed conductor will often work, particularly when ambient sunlight is present. Creation of a plasma path also requires application of an electric field that has afrequency that is very near to a resonant frequency of the substance being sought. The two signals, (stimulus and response) with a slowly varying phase relationship, create an effect like electrically polarized electrodes in a conductive fluid. When aplasma path is created, a minute current flows, and follows a path of least impedance between the stimulated substance and the transmitter. This may be a direct line, but will not always be so. If the path of least resistance passes through a wall, thelaws of dielectrics apply, and refraction may occur, changing the apparent direction of the path. In fact, the path may split into two, as has been observed, where one path can go directly through a door, and another through an air space beside thedoor, simultaneously. In a preferred embodiment, an infrared (IR) laser is used to trigger a stimulating plasma path, stimulate the target substance, and detect the electrical response, all in a single instrument. Additional theoretical work has been done to better understand the propagation phenomenon in terms of quantum physics. A simplified explanation likens the air molecules to tiny energy-wells, physically separated in space. IR energy, such assunlight, partially fills the wells making it easy for energy from a source, such as stimulated substance molecules, to travel in any direction, depending upon the potential gradient, like balls on the slope of a tilted surface. Also by Detection of the Electrical Response Signal Once a path, or duct, has been set-up using the electrical fields generated by the transmitter, and its associated antenna, it is possible to detect the electric response signals using one of several types of sensors designed for that purpose. In the preferred embodiment, an infrared (IR) laser beam source is used that emits in the IR band of 820 nm caused by oxygen molecules in the air. The electrical response signals from the target substance are narrow pulses emitted from the orbitalelectrons of the oxygen molecules as they pass charges along the `path`, and are particularly strong in the vicinity of the transmit antenna element, where the current is most concentrated. The IR detector integrates the pulses forming an analog of thecurrent that passes along the path. Detection is most sensitive, if the IR detector is mounted at a right-angle to the path, but not inside the path. The currents that flow are generated by electrical actions of orbital valence electrons, as they continually seek a stable relationship with themselves and with the disrupting influences of external fields. It should be understood that othersensors may be used to detect these fields, including electric, and magnetic field sensors, to detect the target substance by its stimulated noise field, or to detect the path by its electromagnetic noise field. For example, some of these noise fieldsensors have been built, and used with degrees of success, however they tend to suffer from electrical isolation problems that the IR current sensors do not, because of inherent isolation by optical coupling. The only problems experienced with the IRdetectors are sensitivity to sunlight, and to 60 Hz interference related to incandescent lighting. These problems may be solved using differential sensors, or by placing the sensors inside of opaque housings. Signals can also be optically detected directly, using an Infrared (IR) detector of a suitable sensitive wave-length, 823 nm is ideal. Ionized paths create an IR `glow` that can be detected by looking directly in the direction of a substance,after a `path` has been set-up. This glow may be observed on the ground above, or near, location of the buried object(s). This type of detection may be useful for certain applications, but may suffer from solar noise problems. Implementation of thisdetection method is similar in design to that described herein, but using the IR diode sensor directed toward the suspected location of the `glow.` It may also be practical to build a device that will allow the human eye to observe the `glow`. FIG. 8 shows a typical plasma sensor mechanical construction, with a schematic diagram of a sensor, and a preamplifier, which operates in the acoustic frequency band (up to 100 kHz). FIG. 9 shows a schematic diagram of a wide-band sensor (up to250 MHz). The PIN Diode shown in FIG. 9 replaces the IR photo-transistor shown in FIG. 8. Signal Interpretation, and Calibration The electric response signals emitted from target substances require interpretation before they can be used to identify and locate the target substance. The electrical response signal, without interpretation, appears generally as random noise. This is partly because the signals are themselves responses to random noise inputs. A novel feature of the invention is the algorithm disclosed below for interpreting the electrical response signals of target substance molecules. Substances generally have a finite set of electron energy `states`, many of which are not stable. When disturbed by a transient field, the substance responds by executing a pattern of energy jumps, until an equilibrium is reached. By quantumelectronic theory, this activity involves only that set of energy states, but does not always involve them all. Identification of target substances, using this method, involves a signal processing algorithm that interprets substance noise as electronstate activity, and includes a technique for measuring the characteristic responses of a target substance. This can be done under various conditions, to develop a reference signature which can be used as a match-filter to recognize signals from thetarget substance. The first algorithm processes noise-like signals into characteristic patterns that are used to identify substances. As depicted in FIG. 10, the first algorithm uses a Fast Fourier Transform (FFT), of a digitized signal, and performs a sequenceof mathematical manipulations to produce a "signature" for the target substance. The signature is a spectrum-like table of responses averaged over variables of time, temperature, stimulations, etc. During the detection step, which is used in a secondalgorithm and shown in FIG. 11, the substance signature created during the search, is compared with similarly processed raw data received from the sensors. The comparison process produces a series of magnitudes that represent a likelihood that signalsfrom a target substance are present. An important aspect of the system 10 is the determination of the signature signal from a target substance. One method used to determine the signature signal is to measure and compare the changes in the electrical responses with and without thetarget substance in the target field. By subtracting the electrical response taken without the target substance from the electrical responses taken with the target substance, the actual electrical response from the target may be ascertained. Another possible method used to determine the electrical signature of a target substance is to use a calibration chamber. A calibration chamber is made of a high-strength dielectric, such as glass, that completely surrounds the substance sample. A single conductor is used that allows an Infrared detector to monitor current flowing through a path-of-least-impedance. The substance sample may be stimulated with electrical fields, or by modulated infrared light, which is the preferred method usedherein. The act of calibration involves a sequence of measurements whereby the substance's signature is determined. Substance "signatures", as defined in this disclosure, are of two types, 1) Transmit Frequencies that cause resonant responses in substances, and 2) characteristic emissions, of electrical signals, from substances when they are stimulated at afrequency of resonance. The first type of signature is discussed in the above paragraph titled "Stimulation". The second type is discussed in the following paragraphs. Experimental work has shown that substance, Type 2, signatures may change over time. Work remains to determine what parameters cause the observed changes, but theoretical considerations make temperature, and barometric pressure, to be suspects. Other possibilities include the concentrations of various gasses in the air-mixture, such as oxygen, nitrogen, and carbon dioxide. In a worst-case scenario, it may be necessary to do periodic in-situ calibrations using a known sample of the targetsubstance. Recent work with the high-frequency techniques have resulted in a simplified detection algorithm, due partly to better separation of substance response frequencies. The changed algorithm Flow Diagrams are shown in FIGS. 8 and 9. System Considerations For some requirements it may be desirable to have a fixed omni-directional receiver antenna. For those applications, a receiver can be combined into the transmitter in such a way that any path that sets-up will be detected by the presence of acharacteristic current flowing in the transmit antenna feed circuit. It will be possible to design such a system to continually monitor for the presence of any given substance, and provide warning signals when such presence is detected. A possiblescenario could be to transmit multiple stimulation signals, and monitor for the response signal(s), that indicate the presence of selected target substances. Automatic location of an intruding target substance is possible with increased complexity. Operation Description FIG. 2 depicts a first embodiment of the system 10 that uses two receivers 20 that determine the target substance location by triangulation. An operator first selects a stimulus frequency, based upon the signature signal analysis of the target substance 70 to be located, and adjusts signal source 30 to provide an IR signal 32 of the desired modulated frequency and amplitude. The IR signal is transmitted by an voltage radiation source such as an antenna 40 or to an optical radiation source 60,such as an ionizing IR laser beam source. Upon activation of the antenna 55, or optical radiation source 60, a probing signal 25 is produced that stimulates the target substance 70 and causes it to generate an electrical response field 80. Theelectrical response field 80 causes a local disturbance field 85 in the earth ground 15 by electric induction, that is opposite in phase to the electrical response field 80, thus creating a local disturbance field 85. The electrical response field 80and the local disturbance field 85 thus effectively create a dipole antenna. Two ion-plasmas 25 and 27 are formed that generate two signal paths, so that currents flow through the air 96 to the transmitter terminal 55. Note that the impedance of theEarth's soil is orders of magnitude lower than the impedance of the air propagation medium, so that ground impedance losses from the ground current 22 may be neglected. Transmit elements 33, and 37 (not shown in FIG. 2) provide ground returnconnections, so that current loops are completed back to the target substance 70. This atmospheric current proceeds as charges are passed from molecule, to molecule. Each transfer creates a pulse at InfraRed wavelengths, producing signals which may besensed by two IR detectors 65. The two IR detectors 65 are connected to a preamp 67 that amplifies the signals and digitalizes them for further processing by a data processor 75. The first processing algorithm 66, shown in FIG. 10, is used to detectthe signature signals that are shown to the operator on display 90. A second embodiment of the system 10' is shown in FIG. 3. Several means exist of instrumenting the OLER effect, so that multiple options exist for optimizing a system design. FIG. 2 shows a system 10 that senses two ion plasma paths 25, 27, anddetermines the position of a target substance 70 by remote triangulation. In FIG. 3, a single plasma path 25 and an electrical field detector 95 are used. Such a system 10' might be used with a portable electrical field sensor 95, and a fixedplasma-path sensor, not shown. The plasma detector (not shown) could sense the direction of the substance, and the combination of the two sensors could be used to guide an operator to the exact location. The propagation velocity for the electricalfield is much faster (light speed) than the plasma path (acoustic velocity), so a delay/correlation technique might be used to determine the approximate range of the target substance. A third embodiment of the system 10'' is depicted in FIG. 4 that includes two plasma detectors 50, 50' that are also used together to determine target position by means of triangulation. The system 10' can be used with, or without, a stimulationtransmitter, which is useful if searches must be conducted at night. Hardware configuration of such a system 10'', without transmitter, is shown in FIG. 5. The plasma detectors 50 may be hand-held, or tripod mounted. A typical mechanical configurationof a plasma detector 50 is shown in FIG. 6, with a circuit diagram depicted in FIGS. 7 and 8. As shown in FIG. 7, the plasma detector 50 includes an infrared (IR) diode 51 mounted in a short tube 52 made preferably of stainless steel, or copper. The infrared light diode 51 produces IR light that ionizes oxygen molecules 53 inside thetube 52, generating a conductive plasma 54 within, and in front of the tubing. The tube 52 is electrically connected to a ground, or usable substitute such as the human body. This plasma 54 acts to provide a terminal for connecting to substancesignals, much like a metallic terminal in a conductive fluid, except that the plasma is directional. When potentials are present, currents flow, and in the plasma as currents flow, pulses of IR light are emitted. These pulses are detected by thephoto-transistor 57, mounted on the distal end of the tube 52 at a right-angle to the plasma 54. FIG. 8 is an electrical schematic of the plasma detector 50. The photo-transistor 57 has a sensitivity that peaks in the IR range, according to theemission spectrum of Oxygen (822 nm is ideal). The photo-transistor 57, in its circuit, detects the quasi-noise signals of stimulated substances in the pointing direction of the plasma probe. The signals are amplified, and passed to the analog todigital Computer interface, where signals are processed as described in the section on signal interpretation. Display can be as simple as meter deflections, or as sophisticated as an intensity vs. position plot, depending upon design requirements,cost, and complexity. An IR sensing PIN code shown in FIG. 9, with appropriate circuitry, may be substituted for the photo-transistor shown in FIG. 6, in order to obtain a wider operating band-width. The circuit, shown in FIG. 9, provides usable signal band-width to200 MHz. It appears that Signal-to-Noise Ratio is better at the higher RF frequencies. So now let's study this instrument and maybe we can build something equivalent. Also for the skeptics here is some information which is VERY similar to what Esteban and others have been saying ALL this time. Regards

I am not saying detection of substances by infrared is complete bogus idea, i am just pointing you on fact that it is not necessary true and real all what have been patented so far.
However; detection of substances by infrared is not usable technique in our domain - exploring buried metals etc.. How could you possibly expect IR waves to penetrate the soil? Or...you gonna repeat same old theory about airborne substances, especially over the areas with buried metal?

Only concept i can accept, relating IR, could be IR (with relative remotely range) temperature monitoring. So theory would be; if there is huge metal deposit in soil - temperature will change on soil surface, over that place. So it is possible to observe, monitor and read those temperature changes and variations with use of some IR based device..
"US army" as Hung said, could possibly have in use such or similar device and i don't have doubts in that..

But than again...many other factors (along as metal deposits) can also affects soil surface temperature...
So how to be sure what's underground at that spot? Was it metal deposit, was it huge cavity, was it water deposit..???
