Hello Beth - sorry I took so long to answer. Anyhow I hope the following helps. I found a good web reference to the use of thermography in diagnosis of horse ailments which explains a little of how it is done and how it is useful.: http://www.manepo ints.com/health/0498thermogr.html I also found this site which explains more about the modern thermal imaging cameras and how they work: http://x26.com/infrared/image s/fpa.htm I think this site will give you most of what you need regarding the physics of the cameras. The main trick is to make the CCD’s (charge- coupled devices) used in video and still cameras selectively responsive to IR light as opposed to visible or UV light and at the same time be sufficiently sensitive for practical use. If these sites leave you with further questions, please e-mail at email@example.com
