Calibration of thermal imaging systems based on matrix IR photodetectors

The article presents a set of calibration techniques for thermal imaging systems calibration. The proposed algorithms allow high-precision calibration of the IR photodetector with finding and subsequent correction of the entire spectrum of defective pixels: by noise, amplitude and sensitivity. Part of the work is devoted to the development of methods for correcting the influence of ambient temperature on the optical system of a thermal imaging channel, which helps to prevent the effect of super saturation of the IR image pixels.
