Real time fourier hologram recording in photopolymers with phase response

摘要

The results of researches of phase Fourier holograms recording on the self-developing photopolymer PPC-488 with a photosensitivity in a range lambda = 400 -500 nm presneted~1. It is shown, that due to non-stationary energy transfer between recording and scattering beams and, accordingly, the noise holograms amplification essential decreasing of the signel to noise ratio (SNR) has place at relatively high efficiency of Fourier holograms(more than 50
