Thermal Imaging Technology
 Since thermal imagers sense infrared energy which varies with the temperature of
objects in a scene, the image generated provides a thermal signature of the
scene. This image can be displayed on a standard video monitor.
 Infrared energy from objects in a scene is focused by optics onto an infrared
detector. The infrared information is then passed to sensor electronics for image
processing. The signal processing circuitry translates the infrared detector data
into an image that can be viewed on a standard video monitor.
 All that means is that IR to a thermal camera is like light to your eyes.
