Paper Abstract

An experimental model of an adaptive imaging system for compensation of large-scale phase distortions under conditions of strongly anisoplanatic imaging is studied. We investigate adaptive compensation of phase-distorted extended source images using new types of image quality criteria. These image quality criteria are dependent on the Fourier spectrum of the image, and can be obtained using a coherent optical system. For adaptive control of a ten electrode continuously deformable bimorph mirror, simple gradient algorithms for image quality criteria were applied. We experimentally demonstrate the efficiency of large-scale phase distortion compensation for extended and complex targets.
