Abstract
Operation of a photodetector in an infrared microscope has a number of features preventing the application of calibration methods known for thermal imaging devices. A differential method of calibration is proposed which gives an opportunity to consider the nonlinearity of the transfer characteristics of the photodetector reading unit and electronic path and the variation of the background radiation flux.
