FIELD: holography. SUBSTANCE: holographic device presents correlator in which registering medium is mounted behind amplitude rejection filter and is used for recording of holograms in real time. Correcting amplitude filter is put close to matched filter. Aberration of system is compensated thanks to double passage of light over the same path but in opposite directions. EFFECT: improved efficiency. 1 dwg
