Cooled Thermography Cameras

The energy of the material, causing a change in electrical conductivity, voltage or current. By cooling these detectors to cryogenic temperatures, they are then very sensitive to incoming infrared radiation. Sensitive to very small temperature variations, these cameras are very useful for the observation of fast transient thermal phenomena.

Les détecteurs les plus utilisés actuellement dans les caméras refroidies sont l’InSb, le MCT et le SLS. Les caractéristiques typiques des caméras refroidies sont : Sensibilité très faible (détectivité) <20mK, Temps de réponse très rapide (environ 1µs), Fréquence d’acquisition élevée (jusqu’à plusieurs kHz) & Possibilité de déclencher précisément le détecteur.

Cooled thermography 

Depending on the field of application and the various advances in research, visible imaging has been extended to other spectral areas / wavelengths, with the emergence of new types of sensors: InGaAs, InSb, MCT, microbolometer ... A cooled thermography camera is a measuring device to display the heat waves emitted by a body and which vary according to the temperature of it to understand the thermal behavior. Two types of thermal cameras exist: cameras with cooled infrared sensor and uncooled infrared cameras. The infrared camera with a cooling system is mainly used in environments that generate heat. Cooled Thermography Cameras: In the MWIR and LWIR (thermal) infrared bands, the infrared signal comes mainly from the objects' own emission. It is therefore directly related to their temperature, which allows to make infrared thermography. The sensors generally used in the MWIR band (InSb or MCT) are cooled by Stirling engine and have very good sensitivity.
