5. Key features of uncooled detectors
The 1 website highlights, whatever the principle used for the thermal detector, the two essential parameters of thermal insulation (or resistance) R th and heat mass (or capacity) C th of the assembly consisting of absorber and thermometer. These parameters determine the temperature rise of the absorber and therefore the value of the signal delivered by the thermometer, and the speed of response to a variable infrared flux.
The electro-optical parameters most commonly used to characterize uncooled detectors developed for imaging are NETD (Noise Equivalent Temperature Difference),...
