Can't you just disassemble a digital camera and take the IR filter out?
No. IR covers a lot of ground, basically from DC to (near) daylight! The silicon sensors in video/still cameras are sensitive to near-IR. Far-IR, heat, requires a whole 'nother level of involvement! Near-IR used to be accomplished with special film, and black-appearing filters. (I have one.) Thermal imaging, when I last played with it, was a camcorder-ey device with an internal liquid-helium cooling system (or so they said) like an air conditioner, and ZnS lenses. Looked like gray plastic, not glass. Price was on the order of 1/2 year's salary for one of the engineers. Was pretty cool to put your hand against a heating duct and then see the residual image fade out over a minute or so after you removed it. The display used false-color to show heat levels. -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com All posts are the result of individual contributors and as such, those individuals are responsible for the content of the post.
