Development of an algorithm for calculating the energy concentration of infrared optical systems taking into account the charge flow effect in a photodetector array

摘要

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 mu m). 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 mu m is considered in depth. (C) 2020 Optical Society of America
