OPTOELECTRONIC UNIT Russian patent published in 1998 - IPC

FIELD: optical instruments. SUBSTANCE: device has primary and secondary mirrors with adaptive error correctors, field optical system, beam receiver, electronic reading circuit of image receiver, wave edge detector, system for control of adaptive error correctors, which are designed for processing program instructions from synchronous control controller for non-spherical shape of correctors and correction of non-spherical shape of mirrors for corresponding correction areas of image. Controller may be designed for following function of reading image areas which conform to condition of optimal quality correction for given values of non-spherical shape of both adaptive corrector for each area and for reading images from said areas. EFFECT: increased size of corrected image. 2 cl, 2 dwg
