Re: Looking for Meteorites with Infrared binoculars

Gene, I can't really argue very heavily if this idea would work or not, but I 
do know the gadget we played with was sensitive enough to clearly pick out 
the footprints of a person that casually walked by wearing boots. The heat 
difference between the floor and the boots couldn't have been all that great. 
Besides noting this in an environmental training building with room 
temperatures at around 500 deg F., it worked and looked the same in an 
airconditioned room as well. We all played with it each being amazed that it 
was able to do this. I don't know how long we could still see the residual 
footprints, but they were still there after a couple minutes at least, though 
getting weaker when we were thru getting our fill of looking at them. It 
doesn't take long to get bored looking at one's footprints really.  :o)

If such a scheme should work, I would think the best time to use it would be 
perhaps the first few hours after sunset while heat is being re radiated? I 
believe the ground absorbs the various sunlight frequencies during the day, 
but somehow converts what has been absorbed into infrared to be re radiated 
during the night? Perhaps this heat(heat is another word for infrared by the 
way) from the ground is more readily absorbed by iron like objects to show up 
in such a device more prominently than the material in the natural 
surrounding?
