Paper Abstract

A high-resolution space-born Earth observation adaptive optic system contains a sensor of wave aberration in its exit pupil. The output signal of this sensor is used to minimize the aberration in such or other feedback loop. The complexity of known wave aberration measurement techniques stimulates the search of alternative methods, one of them being considered in this report. The proposed method of wave aberration measurement is comprised with the following steps: Taking the measurement of phase characteristic of the optical system based on the current Earth surface image analysis. Calculation of the unknown wave aberration function using the measured phase characteristic as an input data in Gerchberg and Saxton algorithm. The problems of the further investigation of that measurement technique are discussed.
