Correction of segmented mirror aberrations by phase conjugation and dynamic holography

Abstract

A problem of designing laser telescopic systems with the dynamic correction of distortions brought on by individual components (mainly, by the large-size primary mirror) is so far the issue of attention. Systems of such kind are typically employ a special diffraction structure on the surface of optical element to be corrected thus providing nonreciprocal propagation of the beams in a system incorporating a phase conjugate mirror as well.
