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 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 ....

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 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)
