The cameras show captures images of different colors based on their surface temperature. IR Cameras are used to conduct inspections in homes and factories, to establish whether certain structures and systems are in good condition. For many years the photocathode was the only practical method for converting light to an electron current. As such it tends to function as a form of 'electric film' and shared many characteristics of photography. It was therefore the key element in opto-electronic devices, such as TV camera tubes like the orthicon and … See more A photocathode is a surface engineered to convert light (photons) into electrons using the photoelectric effect.
