1. Thermal detection principle
Two types of infrared detectors coexist: quantum detectors and thermal detectors.
Quantum detectors are based on the measurement of a current generated by the creation of electron-hole pairs following the absorption of infrared radiation in a semiconductor material matched to the wavelength to be detected. Thermal detectors, on the other hand, are based on measuring the temperature rise of a material absorbing the infrared radiation to be detected.

Directory
We need to distinguish between the small number of developers of uncooled infrared detection technologies and the large number of manufacturers of systems or cameras based on these detectors. This box gives an overview of the players involved in the development of uncooled detection technologies. These players supply the market with detectors or modules (detector + implementation electronics) for infrared systems.
