7. Camera integration of uncooled IR detectors
7.1 Correction of non-uniformities
Each pixel of a detection matrix shows slight differences in response and continuous level. To present quality images, it is therefore first necessary to correct this pixel non-uniformity. This is done by presenting two black bodies of different temperatures to the detector in succession. By acquiring the continuous output levels of each pixel for the two blackbody temperatures, it is then possible to correct them in terms of continuous level and gain to obtain the same output signal for all pixels for the blackbody temperatures considered ( 24 ), according to the following relationship.

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.
