Default YES DIGITAL CAMERAS CAN SEE UNDERGROUND EASY AND LIVE

it has been 2 years working on a small project, the digital camera that can see a live view underground way down to 40 meters by just doing some modifications to almost any CCD image sensor or CMOS, cameras.

I noted discussions since year 2012 regarding this weird phenomenon a guy with some sort of black plastic bag in Iran gives you a clear video of what is underground and others are requesting help from the forum many of you did not believe the stories just like I did 2 years ago until I decided to make one my self.

the result will amaze you all.....
the camera can go as far as we tested at 40 meters the image is sharp and clear and so magnified ina a form that you can talk to your self although you can find some inconvenient bugs that can't control, it works great
I'm sending you guys some videos and some other links for others that they made this camera works fine I did not see anywhere in the world making this tech besides turkey Jordan Iran Iraq Lebanon,

from the view of science, it was clear by some universities and researchers that this is so different than 3D devices and other GPR instruments it is simply the use of optical imaginary or virtual view of the focal point while we focus in and leaving behind the real view now somebody will tell me hey> the CCD image sensor can't see the virtual image scientist hardly reached this image sensor in 2018! the answer is the trick of how to make your camera able to capture this image.

now making and modifying such a device requires some skills "not much" in electronics but more knowledge in physics and some principles of radiation patterns that infrared can cause when they cross out when they are in the same phase and wavelength especially when they come out from the same source, splitting the beam then merge it right in front of your camera lens.

a brief and fast explanation that may most of you understand the main concept but in order to do what I did you may need some time if you really want to have this tool next to you when looking for something on the field I'm not saying it should be a stand-alone device it is a must to add on to what you have to make sure that everything is ok as some friends of mine detected buried mines underground using this camera it saved their lives
will talk about the advantages and disadvantages of such a camera

the real view you will see is real and as if you are just filming the target right up the object as it if was in front of you, some times color can be noted also in some sort of metals the size and shape of target magnified so you can see small details even if your target is tens of meters underground no matter what type of soil as long as some metal man-made or any man-made artifact is under the ground the camera will see it, the best and easy find if cavity with metals inside then it is a real goal.. imagine the camera is hung inside the cave in the top of it and is looking downwards and you are watching live! but the camera in fact is with your hand above the ground half an inch only from the dirt.

what is not so good if you don't make you camera excellent fit it will lead you to the unidirectional way that will show you something but, in fact, it is somewhere around you in a radius could reach 30 meters or even more and the camera then will become absolute due to the incorrect directional viewing for example if your camera directed with a tilt to the south and it is easy to show you a cave behind you and you can enjoy viewing the target but you will never know how deep or where exactly if you don't balance your camera will enough by some tools

again the camera easy to make it but in order to have a great deal you need to make it right

get yourself any of the shelf USB digital camera especially those old laptop cameras from Logitech I prefer the CCD image sensor rather than CMOS
disassemble it ake out the UV-IR filter sometimes it can be attached in top of the image sensor or in other types attached behind the lens nearby the sensor
take the lens out and you may find inside 4 or 5 lenses keep only one the convex it may be the second from the front of the lens or the first one keep the little black plastic whole away from the lens about 9mm "this will help not to let much light to enter and help to prevent the Corona effect " please read about corona program 1968 USA"
attach the lens in a black tube just the size bigger than your image sensor in diameter
50 mm long that is about almost 2 inches let the lens exactly 50mm away from the sensor and the only part in between is the little black plastic piece and it will be near the lens about 9mm that is the most focal length of convex lenses in such camera
the system is using only one lens and far away 50mm in order to have an almost microscopic image in your laptop once you are done test the image when you place any book from inside letters you should see the one letter as big as 3 or 4 times your monitor in other words the magnification is almost 200 times or even more you may need some sort of light to test
if your image is sharp and clear fixup your black tube by any none metallic epoxy on board of the camera having much care not to let any drop over your image sensor you may need to fix the lens inside the body that was originally having the lens and other lenses or you may find your way to fix it in front of your black tube
step two
find 2 or more LED 940Nm infrared and get the resistor corresponding to let them both in serial if we get 5v out the USB cable"don't use the LED outlets was originally installed on your board the current is designed for white LEDs and your infrared LEDs needs less power and current" then you may need 0.380 Ohm you can find on the net a calculator to help you hay many ohms the size of your resistor to let 2 LED 5mm infrared
in serial powered by 5vdc, it is important to have them both the same kind and freq in order to produce a pattern to generate radiation "small amount don't worry unharmful"

place the LEDs so close to your lens in almost 30 degrees that will make your spot beam hits almost 9mm to 12mm in front the lens which is the focal distance of it and not to let the LEDs get further more than the lens means nearby the lens and tube but with a degree and will not exceed the length of the tube otherwise the ground will damage them

once you're done making a little test on the book the same letters you tested and see if you get a clear image if ok now get a blue congo sheet cut a small round piece and find a way to attach in front of your lens or find a filter of 940nm and use it but you need to find a ring to separate the lens from the LEDs otherwise you will get some portion of the light reflected into the image sensor you can then use to cover the camera any polarized lens not magnified
but your camera in a plastic tube and get a rubber of front car axel may be large enough about10 or 15 cm this will be set on the ground to help you maneuver and search at the same time to prevent any visible light to get to your sensor

now your camera is ready, place it nearby any known manhole and is a must to find soil and start looking slowly and in a circular motion then every once in a while you press down the camera so you will not be able to see the magnified ground repeat the process in going from the real view image to the unseen virtual image until at sudden you will see the void or cavity or metal

good luck guys let me know if your test goes well

some examples of what this camera can do some links to share

YES sure it does since we have seen animals and tree roots also one experiment done by my friend he was able to see a live video of humans in a cave 4 meters below it was a cave with an entrance from a side of a mountain.

still, we need to make some modifications in order to assign a specific frequency that allows us to see only one of our interest, for example, living animals or tree roots will have a different frequency than stones or metals or man-made artifacts.

this requires to set your filter and source of light accordingly

I did try to upload some videos anyway to do it to this website?

Good evening,
You said that your friend managed to capture a live streaming video of men in a cave 4 meters below..
Question: Could you provide how many minutes had lapsed before he was able to receive the streaming video?? I mean, after he placed the camera on the ground and started searching for the cave, how many minutes have lapsed before he started receiving the live video?

Thanks

It's a trick. Blow up the soil particles. And make it Ka scattered rocks. It does not penetrate. Just blaster. Place a handkerchief under the camera and watch. Do not break it. The napkin particles get bigger.

YES, DEAR, it took a while as I recall some this it took 10 minutes and once it took me 20 minutes to get down to the drainage pipes near home the fastest time I recorded was 5 minutes inorder you get switched from the upper view to underneath ...

if you don't believe it then kindly please learn and then you will say wow....

yes at the beginning it is true you will see magnified dirt then.....what is gonna happen next is what we want you to see...

Good evening,
Thanks for reply.
To start with, I'd like to comment on your reply to one skeptic who said the camera will catch the dirt or soil granules and magnifies it, and you confirmed to him that the camera will pick up the dirt granules first then it will jump to catch whatever is underground, whether be it metal or void.. Yes you are right.. this what happens with my Gamma Ray Camera..
Now I will comment on your reply concerning the time it will take to start seeing the streaming live video .. In my gamma camera, first of all it has nothing to do with pinpointing zero spot of target whether metal or void, and therefore, it depends actually whether you are precisely on top of the void.. For example, two years ago when I didn't have other pinpointing target-locating tools and I be for example 5 meters- horizontally away from it, then it used usually to take 10-15 minutes for the camera to catch the target, but since six months ago when I learned to pinpoint zero spots of targets by using other tools, hence when I use the camera on the determined zero spot of man-made void (cave,grave, etc.) of 30 meters deep, it took me only less than 30 seconds to see the void.. which means that I'm precisely on top of target.. this is why I asked you how much time it took your friend to actually see the streaming video.. Again, I'm clarifying issues related to my gamma camera, and not necessary related your camera.

Thank you..

No no no Not is trick , I know for this Method and is Real ,
Please not comment so that is trick .

When I comment for this Device before many years , very humans Says that is trick , but I know that not is so ...

Hmmm , this is Gamma camera ?? (gamma light) or Works with different light ...

Thank you..

Dear Elhit, you are right regarding the time and misdirection of a target or the zero point....

before I start talking about the issues I faced I would like to thank you and say thanks to HUMHUM for being open-minded and ready to share science experience that I think it is so hard to have a good explanation on this phenomena ..

TIME issue..

now as far as I know that there are many reasons behind this real viewing it is somehow related to emissivity, Phonon "sound waves" photon excitation and the source of light that could produce a small amount of radiation due to it,s directional crossing that produces a pattern in a form of circular waves that each time hit a matter and get back to the lens of the camera and back again to the same point it causes one circular Ring this ring excites the molecular structure "he outside shape or the surface of it" then it's radiation becomes much higher than other natural un-dense matter like soil particles and due to the solid mass of man mad made metals ..so the light is in some wah is transferred of it is form from Particles- and waves " as modern science approved the theory of Albert Einstein who said light is either Particules or waves or both"
TO electrical pulses then at the top again it will be retransformed to photons when,,, your camera needs photons to see an image the image sensor reads them and generate electrons of each pixel in CCD the whole frame is translated to electrons but in CMOS each line is done separately,, now what this has to do with TIME delay until you capture an image...? this is, in my opinion, is the propagation that happens with the help of other frequencies nearby, for example, such cell tours microwave transmitted to your search area, satellites and radio frequencies all are responsible to help your camera do this.. but the dealy is as I mentioned rings happened after each 1 to 2 mm depth " attaching an article about rings#1"
the study shows that each ring takes some time so if we calculate 4meters depth that's 4000mm each mm depth needs some a few milliseconds total could reach minutes if your target way down ...

KIND OF THINGS YOU CAN SEE
I mentioned Man-made Materials this includes plastic metals glass etc...
but we noted that animals are easy to be seen by this method and tree roots my first experiment I saw a cockroach in whole sharp and clear I said let me check below my camera that could be a little one...but suddenly big Mouse walked behind the Cockroach !!! here I realized that my view was way down "2meters" under the surface because my camera is magnifying things to 200x and mice will never fit in between the lens and the surface at that time my focal distance was 0.9 cm or 9mm only so how the heck would a Mouse fit under the plastic cup of my camera? then I started to note the tree roots an example of a nearby tree was an Olive tree I noted the roots "ONLY" LIKE if I was sitting in a swimming pool and the tree is over the water surface and the roots are extended in the water,,, my images "in my computer recorded by a photo from my cellphone to the monitor that I was using, at that time I didn't use a laptop and USB camera I used CCD camera with infrared 940nm .. so it is clear that we can detect also Limestone easy the whole shape and even we can see them glowing ....

DIRECTION AND ZERO POINT. Unfortunately, till now I couldn't determine the image direction exactly and that due to the hand made LEDs and the hand mad alignment in front of the camera so when I asked a Dr. in Physics he mentioned that we shall align the LEDs by a machine that uses a Prism to make the radiation waves perfectly that helps us not to see things behind or aside, another issue was the image size? The size of an object is not the same as you will see it tomorrow. as we magnify the surface we could never see things near like 1 meter or less ! objects at depth 1 meter or less, I had to step aside like 3 meters away and direct the camera to the direction of an object " that is with this type of magnifying camera other types like original sony camcorders could see the wires of underground at a depth less than 25cm ...

now I have one simple question for you, we are searching for nondestructive methods to serve us in our research including body imaging that china has done so already. by using Infrared and near-infrared Mid-infrared that all are Non-Ionized radiation why you are using Gamma? since gamma is extremely dangerous, or you are calling this Gamma? to generate Gamma radiations you need some instruments and as far as I know, normal CCD and CMOS sensors can't see the gamma or x-ray without a projection screen! our cameras on hand are sensing from 250nm up to 1200nm and you went all the way to 1nm ! could you please explain what LEDs you're using?

hope we can reach to a point that will allow us to use this high technology to find what is exactly each individual interest of viewing underground friends I have in the field of agriculture, ore mining, treasure hunters, archeologists, I would say 2D imaging is great because is simple and within reach of everyone 3D is extremely expensive and you won't get a real image as what we achieved.

worth it to start constructing your own camera my topic is to encourage all of you to share knowledge and find your self the mystery of this camera.

All the best

Hi , I think when transmit XX Light of ground and you wait , this Light first heated ground and moving slowly slowly so like (Air) weather conditions up to object and Reflect from it back to Camera in minimal signal , here will need x200 Amplifier , if light comes across any live creature, it will perceive or absorb its heat and vibration more comfortably, for more visible .

Remember what says Esteban for IR Light (LRL) , all story is in this method , but here instead IR nm Sensor have Camera receiver with wide band . Here very important is wavelength of light for more penetrading and and for visibility .

I Think so ... , but can be and other ...

An idea for the author of the article. Replace the infrared diodes with laser infrared diodes. They can be removed from an old CD. Then it will be possible to precisely position the two rays at one point and increase the radiation power.
