Dynamic holography using Brillouin enhanced four wave mixing for distorted image compensation

Abstract

The dynamic holography is considered as one of the most promising techniques for correction of dynamic aberrations in large-aperture optical systems when operating in near IR range. The use fluorocarbon Flourinert FC-72, characterized by Brillouin nonlinearity, for recording the dynamic hologram has been demonstrated experimentally. Ten times improvement of hologram's diffraction efficiency(more than 50 %)compared to previous studies while keeping compensation to diffraction limited quality has been recorded with Brillouin enhanced nonlinearity for writing and reading holograms. Perspective of the use of Brillouin enhanced dynamic holography for nonlinear compensation of optical aberrations has been presented.
