you can work without any filters and let all wavelength pass .

Dear Darkman. one of the main reason why I use a heavy filter that blocks all visible range and a small portion of the infrared 720nm-940nm is that I don't want to see the surface and that can be done by only making the infrared beam crossing at some angel that will not illuminate the surface, one of the pictures I sent is that one with SUPER SHARP PATTERN that has a dark ring in the center is simply when you go down to the viable point distance"the focal point", not enough infrared light reflected and enters the image sensor so you won't see the ground surface.

this could be done by sharp beam LEDs with a small angle less than 15 most LEDs at that range in the market are 30 degrees or 60 degrees that are used in remote controls

so when an image comes means the underground image is confirmed, not the microscopic image that the camera will show you. on the other hand yes I heard from my partner that once he tried not to use the filter and he made it.

in case of chemical reaction yes sure the catalyst can make the reaction up to 1 million times faster by using less energy.

but in the case of A photocatalyst is a material which absorbs light to bring it to higher energy level and provides such energy to a reacting substance to make a chemical reaction occur. From: Bioscience and Bioengineering of Titanium Materials (Second Edition), 2013

also many kinds of research about radiation effects on catalysts

yes in nuclear reactors they are using this catalyst to attract radiation that harms the imaging system.

friends, I made a little experiment. The first studies that are really working are positive. I would like to thank everyone who shared this information and supported the subject. it really works

you are so kind, you most Wellcome

Great news, have you tested on a well-known target?

sorry for the delay on answering you

The real challenge on this topic is what is the good combination that will make this project works well, using camera that has a different specification will need a different setup
for example, I used the whole parts on different image sensor I never got the same result

remember testing your camera must be in a place that you know what's inside.

Hello my old friend this video is from your friend Emrah.
I m interested to your Opinion Brother

hi Mr Nicolas ..



what did you think about using ultrasonic wave with the system ?


i think you know more than any one here about this type of wave's >>



thx

I think I have an exact explanation of the phenomenon with the camera. There is nothing new under the sun. I understood why it works for someone, it doesn't work for another and what needs to be done to work - to see underground.

No, I just put trial metal. I did not go to the field test. it's raining :)

Thank you buddy. I will contact you when I pass more detailed videos. thank you so much.:)

As a Result can we Say that , Cosmic wave ray or other Wave(without RF or Ultrasonic transmiter) when penetrade and Reflect from underground Object (if converts wave) , can Receive from Camera nm Band . ?

Very Good Dear Nicolas and Congratulation of Emrah , I everytime believe and know that this system is working .
more good will be when get Video from more deepth Object 10 or 20 m ,but need be with good resulition .

Dear Dragomir , once you have learned (щом сте научили) all Details for Working of this Camera system , and when You build one from this Camera , can send here one Video for see result .

I haven't taken photos or videos because I don't have any free time at the moment, but I think I understand the principle on which the camera works. From all the information about how the camera works, said here, everything is already clear to me. I can only tell serious people what and how to experiment.

Can explain more about how it work or not freind

More than 10 years ago, in connection with the operation of a device, I received information from a very great Russian specialist, which I promised not to disclose. In this information I received is the principle of operation of the camera. The Russians have a device that works on the same principle, but its principle of operation is also not disclosed. This is a discovery of its inventor, but it is kept secret. Only one colleague from the forum knows something from me, but not everything.

Thats mean there a secrit to make it work ???

My dear MAYBE YES! image sensors can capture besides the Nm band, Alfa and beta particles also, but sure not the RF itself unless otherwise is converted, what I'm sure is that RF and other waves in the spectrum what is about to excite the surface of buried items subsoil, this excitation in a way or another is helping the IR radiation "emissivity" to be viewable at the surface of the ground by taking a path called in modern physics snake-wave photon in absorption only not in reflection nor in transmission.
the wave is converted from a range to reach Nm band, could be! WHAT called my attention is the source of light in the image that has Shadow just like a flashlight! with different sides.

we are trying to gather all possibilities for this phenomena

external radio waves, waves from the sun, waves from the core of the earth, etc..

My Dear, we know that most Iraqi scientists in"in physics and nuclear science" graduated from Russa, the whole idea spread out from your country, because in Ukraine Russian used this camera! so knowing about it any information could be useful for those serious people and those unserious people or skeptics any why such a piece of information will do nothing to them! unless I misunderstood your OFFER!

I have seen your posts in the past , seams that you know too much! if you wanna talk we are all good listeners.

my respect Dragomir.

Physics Questions People Ask Fermilab

Why can radio waves pass through a wall but light cannot?
Hello,
My name is Mike P. and this is my question.

If radio & light waves are both properties of the electromagnetic spectrum then why can radio waves pass through walls but light cannot?



PART 1.

Let me first make sure the terminology we use is right.

The words "electromagnetic spectrum" are used to name a group of waves. Not any kind of waves, ( not acoustic, not mechanical waves) but electromagnetic waves. These waves have in COMMON that they are originated by electric or magnetic processes. But they also DIFFER in something which is called WAVELENGTH. (Simply speaking, their size.)

Check out our pages of light on the following web page

http://www.fnal.gov/pub/inquiring/more/light/index.html

( As an analogy think about "senior class". It is a name for a bunch of kids going to the same school and being roughly about the same age. However, they are all different. The differ in their weight.) RADIO waves and LIGHT waves are both PART of the "ELECTROMAGNETIC SPECTRUM", just as say JUDY and JOHN are PART of the "SENIOR CLASS".

Got the analogy?

Great!

PART 2.

Ok, now let us take a look at your question. I decided to give you two answers. One intuitive and not very precise, but still demonstrating the idea, and a second one, more precise and scientific.

PART2A.

The first answer uses again an analogy:

radio waves corresponding to a boy
light waves corresponding to a mosquito
the wall corresponding to rain

The answer to your question is hidden in the comparison of the sizes of the above objects.

A boy can easily run when it is rainy. Right? But a mosquito will never fly when it is rainy. Why? Because the size of a mosquito is roughly the same as the size of a rain drop.

If a mosquito entered into the rain, the first few drops would knock the mosquito down to the mud. On the other hand, since the size of a boy is much much bigger than the size of a rain drop, it is easy for a boy to run on the street even if it is rainy.

Now I show you how to use the above example in the case of the waves and the wall. What do you compare in this case?

You compare the size of the waves and a typical size of atoms in the wall.

The size of the waves is characterized by their wavelength.

I am telling you, radio waves are huge waves, their wavelengths are much much bigger then the size of atoms in the wall. According to the above analogy, that is why they go easily through the wall. ( As a boy did in the rain.)

On the other side, light waves are very very small waves, their size ( wavelength ) is comparable to the size of atoms in the wall. And that is why they are not able to go through the wall. ( As a mosquito cannot fly when it is rainy.)

CONCLUSION1: The radio and light waves are part of the electromagnetic spectrum, but are very different. Radio waves are much bigger than light waves (in terms of their wavelength). Radio waves are bigger then the size of atoms in a wall, that is why they go through, while light is a small wave and cannot get through the wall.

Does this make sense to you?

Good!

PART2B.

Before I give you a more precise answer, let us examine what you said. You claim:

"Radio waves go through the wall and light does not."

WELL, THIS IS NOT NECESSARILY TRUE ALL THE TIME!!!

If the wall is made out of glass, LIGHT WILL go through it.

On the other hand, if the wall is made out of iron, the radio waves WILL NOT go through the wall!!! appears

Wow, things are starting to be complicated right?

PART2C.

This leads us to a more precise answer to your question than the one I gave you above in PART2A. The real key is hidden in the STRUCTURE of the WALL. It matters, what the wall is made from, what kinds of atoms and molecules are its constituents. Also it is very important HOW these atoms in the wall are tight together.

As you know, every atom has a shell of electrons. These electrons interact between each of other and also interact with the outside world. The properties of these electrons dictate, whether a certain kind of incoming electromagnetic wave will go through or will not.

Some materials have the electron structure such, that they to be transparent for light but not for ultraviolet radiation ( for example glass, you will never get sun burned behind a window). But you can safely listen radio in your room. Glass is transparent to radio waves.

Some other materials have a different electron structure of their atoms, so they are not transparent for light, but are transparent for radio waves. Let us say a brick wall.

Also, as I said, you can find materials ( conductors, such as gold, iron, silver) that are neither transparent for radio waves nor for light.

CONCLUSION2: The atomic structure, especially the properties of the electron shells of atoms in the wall dictate if that particular wall to be transparent or not for a certain type of electromagnetic wave.
