Abstract

Method of increasing the efficiency and quality of associative (by a fragment) data retrieval in the resulting zero reflective order of a system, composed of a thin off-axis hologram and a feedback mirror, situated in its -1-st diffractin order, is considered on the example of lensless Fourier-holograms. As a feedback mirror an adopted static phase-conjugating mirror is used based on hologram of mutally conjoined waves.
