ADAPTIVE SYSTEM FOR IMAGE FORMATION Russian patent published in 2000 - IPC

FIELD: adaptive optics, coherent and non-coherent systems for observation of extended objects working under conditions of atmospheric distortions. SUBSTANCE: adaptive system for image formation has mirror system, corrector of wave front, forming lens system, beam splitter, image recorder, mask corresponding to outline of undistorted image of observed object, former of controlling signals, amplifier of image brightness, second forming lens system, mirror mask, second photodetector, inverter, adder and switch. Mirror mask is made for corresponding region of substantial values of Fourier optical spectrum of undistorted image of observed object and mask corresponds to proper region outside of region of substantial values of Fourier optical spectrum of undistorted image of observed object. EFFECT: expanded application field, specifically, with a priori uncertainty with regard to outline of observed object and its angular position in field of vision of system. 2 dwg
