 |
| An older model thermal imager was connected to a USB video capture system and thermal images were recorded. The thermal imager is an ISI model 77, which used an un-cooled pyroelectric vidicon tube. A pyroelectric tube can only detect changes in temperature and this particular camera does not have an optical chopper, so the image must be kept in motion. |

Thermal Imager (7/06/2013) 50mm f0.8 lens, 8-12um wavelength.
|
 |
Thermal Imager (7/06/2013) Power switch, video out, brightness control, and pole switch. The pole switch repolarizes pyroelectric crystal if it becomes depolarized by looking at a very hot object or during storage. Camera should be left on for about 45min to heat up before pole system will work properly.
