We're doing some thermographic imaging (looking for irregularities), and since thermal diffusion wipes out any contrast *very * quickly in thin materials, the laser is necessary. Boring heating elements including photo flash lamps are too slow to get good frequency data.
Sorry; should have included that - thin polymer sheets, possibly including other polymer, foil or paper laminations. The exposure time would be very short of course.
Hi,
New to the forum but I've worked a little bit with high power LEDs for some other lighting projects.
I'm trying to put together a moderate power (1+ W) IR (808 nm is fine) LED system to do some spot heating (and eventually line heating, using a moving mirror) of materials in the lab for...
