Abstract

The paper presents an analysis of designing an optical-electronic imaging system designed to operate in a turbulent atmosphere. The optoelectronic system design is based on hill-climbing and phase conjugation technique using a bimorph adaptive mirror and a Shack-Hartmann-type wavefront sensor. The system corrects the wavefront distortion of the laser radiation passing through the test object and an inhomogeneous medium that simulates a turbulent atmosphere. Criteria for restoring the geometric characteristics of the test object are analyzed using the proposed hybrid algorithm, including spatial-frequency analysis of the recorded spectrum.
