Optical detection?

[bureaupro2000@yahoo.com]

Hello, friends!
Could promising optical detection, a future in search of treasures from a distance?
If metals, emit ions that then I could detect infra red spectrum, using a camera with a filter 720nm - 1000nm? David Villanueva explain this: http://www.youtube.com/watch?v=T4JOjqYQZVY
Someone experienced?

Now you are talking!
By till the December i am expecting this to get:

HS-324 actually:

When is cold outside, let's say -10 to 5 degrees, must be significant difference in temperature deeper in soil, let's say 2-3 meters deep.
So, ancient tombs, tumulus etc.. usually are placed at similar depths.
Depending on period, such tombs can be few square meters in size and meter to 3 high.
Let's presume that such tomb is placed just 1 meter deep (know about few cases).
So... if outdoor and surrounding soil temperature is -10 degrees, i bet inside the tomb must be higher for least 5-6 degrees.
At such small depths like meter or two i assume (and hope) that such camera can catch difference which will be visible, at least in shades.
Don't know for sure... but hopefully will check soon!

I've moved this from the Geophysics forum to Remote Sensing, where it belongs.
Perhaps I should have also renamed it to "Optical Delusion".

You think so?
You know my attitude upon LRL, you can't judge me as "delusional" (i hope)?
I don't expect to locate small items on explained way - but i do hope to catch some shaded differences when temperatures are drastically different in soil and air.
Have you payed few minutes to watch demonstration videos made by Flir?
Because i had. Early this spring i ordered 4 DVD's from Flir and got them 20 days after.
I have hours of video material about this matters.
Trust me; it is not delusional at all.
US army (special forces) and special police squads are already having those in their standard equipment.
What do you think: how they located Saddam hidden in that hole?
Think twice before you make any judgment about this.
This should not be moved to RS because it has nothing to do with subjects there.

I see.
Ok, it just reminded me on this what i posted earlier.
It is interesting subject!
I will follow the news.
Thanks for posting that here.
Cheers!

I was referring to the book "The Successful Treasure Hunter's Secret Manual", of which I have a copy.
Have you read it?
It's nonsense.

Ahh that!
No i haven't, but i already heard the same opinions like your, from other people too!

I have respect for all who try to find solutions for the detection ... can you call "Optical Delusion" and this: http://www.auraphoto.com/products/auracam.shtm
Of course we have to materials about ....

Are you sure about that link?

I get this message:

"..The object you requested, /products/auracam.shtm, does not exist..."

[bureaupro2000@yahoo.com]

see AuraCam6000

The link didn't work. Here's the correct one -> http://www.auraphoto.com/products/auracam.shtml

Now I can see I was correct to move this thread. More "funny" aura stuff.

Tend to agree now...
I should start new topic dedicated to Flir cameras...

[bureaupro2000@yahoo.com]

It is interesting to hear more opinions from people documented scientifically, not fraud as Maxfynd http://www.maxfynd.com/ sellers! It sells some cameras, that if you want to find your treasure, movies and sends it in Australia filming, then pay and send you some **** colored interpretations of programs ... same Rangeltell ...

To find exact treasure with camera.... tough!
But to use Flir camera to explore soil a bit more and collect more informations about some soil's features ... it is possible.
Don't pay attention at all on advertisements which containing word "treasure" !
Because such advs are there to "chill your pockets" and nothing else!

[humhum]

Hi to All, ı make several photos try without IR filter .


Before and After

[ivconic]

There is lot to achieve and discover with plain optics and various filters, i agree.
Rife is most known exactly by that.
Light and its "dimensions" are still not fully examined and explained enough.
Our sight is not capable enough to accept all the light features and possibilities that may existing with.
Using filters is barely enough to see just top of the "iceberg"!

I belive can work, but not so good and with large things underground , not small stuff

the temperature gradient is widely used for other stuff... if you remember some pictures of post-WTC attack in 2001 you know what I mean

(is possible even detecting from satellite or airborne vehicles the gradient variations and so large temperature anomalies underground... but NOT small things or masses)

Hi Ivconic
I belive can work, but as I explained above and as you stated: difference of temp from surface soil to underground few meters and large structures and anomalies , not for the small things

regards,
Max

Sounds like several completely different things are being discussed in this thread.

Flir is a real (big time) infrared thermography company. Infrared thermography is generally in the 6 to 14 micron band and has nothing to do with imaginary "metal ions" or near-infrared 1 micron stuff which uses silicon sensors.

Infrared thermography can't literally look underground; however differences in the thermal properties and temperature distributions of soil can result in detectable temperature differences at the ground surface esp. under calm cloudy nighttime conditions.

Snow is a thermal sensor. It is often noticed that over buried structures, snow melts either sooner or later than over adjacent areas. Infrared thermography is a way of taking a snapshot of somewhat the same thing that snow cover indicates. And of course works in places where it never snows.

Infrared thermography is a noncontact method and the distances over which it can be done are basically limited only by the resolving power of the sensing and optical system. It's a basic weather satellite measurement.

So, where does the subject belong? It's clearly scientific and although the natural science involved is that of atmospheric physics, the interpretation of the data includes geophysics. I say it belongs in the geophysics forum.

And, the reason that it doesn't belong in the "remote sensing" forum is because that's the de facto LRL forum, which has nothing to do with scientific remote sensing technologies.

I agree.
However, this thread was originally started with reference to David Villanueva's book, and the use of an infra-red filter to detect gold. That's why it was moved here to Remote Sensing. Later on, Ivconic added some comments about Flir. I suggest that, if you want to discuss Flir, then open a new thread in the Geophysics forum.

I agree also.
The Villanueva book was shown by Esteban here: www.geotech1.com/forums/showthread.php?p=107769#post107769
By the time we got to the end of that thread, it appeared to be clear to me that photos he took to show the farthest infrared his cameras could capture were not showing anything to do with treasure. Instead we were seeing artifacts from reflected near IR same as if it were visible red light. And some of the photos also showed artifacts which appear to be produced by uneven operation of the rollers in a polaroid camera, or perhaps imperfections of the film. In the case of red spots near the center of the digital images, it looked suspiciously similar to the near IR beam that many digital cameras project in order to help focus the lens. I would expect to see the camera project this focus-assist beam considering he had filtered out most of the visible light from reaching the lens.

But the fact is, the near IR that the best digital cameras and film cameras can capture is not in a range that can indicate temperature. Even the night-vision IR is really capturing dim near IR light that is reflected off objects and then amplified so that it can be seen.

In order to actually see images of temperatures, you need a thermal imaging camera which does not see any visible light or near IR. It sees only heat emissions to form an image. We had a forum thread where using real thermal imaging cameras was considered, and concluded that it could be helpful finding treasures in the right conditions. Unfortunately this thread was about a $59 digital infrared thermometer that someone claimed was a valuable cave detector worth thousands of dollars. In the process of debunking the claimed "treasure finding" firmware, it became apparent that you would need a thermal imaging method rather than a simple thermometer to help find treasures. Original thread here: http://www.geotech1.com/forums/showthread.php?t=12806

There is a lot of literature which shows the difference between near IR imaging and thermal imaging done well into the IR band. In the examples below you can see how near IR does not show temperatures, but only reflected near IR light. Then you look at the thermal image made to measure the temperature of the objects and you see a much different image. The colors are then added to the black and white thermal image using software to make it easier to recognize the temperatures. I think Dave is correct. Thermal imaging can be very useful to help locate treasures in certain circumstances.

The diagrams below were taken from the original article here: http://www1.infraredtraining.com/view/?id=40483

Hi...

you think we can detect treasure underground by infrared filter on our digital camera ???

if everyone have this book please upload in here :

The Successful Treasure Hunter's Secret Manual
Author: David Villanueva

Thanks...
