ADAPTIVE OPTICAL MODULE Russian patent published in 1997 - IPC

FIELD: control over radiation wave front or compensation of phase distortions in optical instruments and systems of wide class including industrial laser technological complexes, optical telescopes of various spectral range, optical guidance and tracking systems. SUBSTANCE: adaptive optical module has deformed bimorphous mirror, light-splitting element, modulating mirror, master generator, amplifier of signal of modulating mirror, forming optical unit, radiation detector manufactured in the form of grating of photodiodes and electron amplifier-converter used to form signals for control over drives of dynamic adjustment head. Deformed bimorphous mirror is fabricated in the form of semi-passive bimorphous structure including hexagonal mosaic system of multilayer piezoelectric elements of hexagonal or round shape. Radiation detector is manufactured in the form of hexagonal grating of photodiodes with round or hexagonal light aperture. Hexagonal grating of lenses and set of fibre-optical cables can be installed in front of radiation detector. EFFECT: improved operational reliability. 9 cl, 9 dwg
