Abstract

The main problems of calculating the energy concentration function of optical systems obtained using a test-object image that is measured using a photodetector array are described herein for mid-infrared radiation (3–5 µm). Possible solutions based on mathematical transformations of two-dimensional optical signals are proposed. The effect of the charge flow in a photodetector array characteristic to analyzers of the wavelength range of 3–5 µm is considered in depth.
