Performance analysis of a microbolometer camera with and without Peltier tempera-ture stabilizer

The article presents thermal modelling of a microbolometer detector inside the FPA (Focal Plane Array) camera.This modelling assumes heat transfer from/to the bolometer matrix through the multilayer structure. The Peltier cooler is one of the layer which enables the equalization and stabilization of the temperature below the FPA. The presented model allows to simulate the heat transfer by radiation between the matrix and an object and the impact of Peltier device on the FPAtemperature. The parasitic radiation heat transfer between the detector and surrounding objects resulting in the non-uniformity of the generated signal is neglected. The model can estimate the performance deterioration of a microbolometer camera due to the non-ideal stabilization of the temperature by the Peltier cel
