Paper Abstract

It is theoretically shown on the example of a lensless Fourier hologram, that additional channels of associative data reconstruction are possible in the system, composed of a thin linear superimposed off-axis hologram and a phase-conjugating mirror. Due to the "phase-retaining" nature of a phase-conjugating mirror, partial transformation of noise field components (which are nonlinear on amplitudes of fields and can't be interpreted as an image or a correlation peak) into information field components takes place in such a system. Taking it into account and assuming certain opportunities of phase-conjugating reflection control make it possible to consider the system as a quadratic hologram with modifiable response. Possibilities of data processing by all the channels are considered.
