Glossary

thermal imaging: Thermal imaging is a technology that detects infrared radiation (heat) emitted by objects and converts it into an image, known as a thermogram, which displays temperature variations in different colors. Unlike visible light imaging, thermal imaging does not require any ambient light and can be used in complete darkness or through obstructions such as smoke, fog, and certain materials. Thermal cameras use sensors to detect infrared radiation and generate images based on the temperature...
electro-optics: 1. The branch of physics that deals with the use of electrical energy to create or manipulate light waves, generally by changing the refractive index of a light-propagating material; 2. Collectively, the devices used to affect the intersection of electrical energy and light. Compare with optoelectronics.
