FIELD: optical television equipment. SUBSTANCE: holographic television device has laser, object and reference channels, hologram forming unit, hologram reconstruction unit. Quantum amplifier is installed in reference channel. During process of recording of images of object the latter is illuminated with laser radiation of object channel. Reflected radiation goes to hologram forming unit and into reference channel, amplified there it also goes to hologram forming unit where formation of holographic image recording of object takes place on intermediate frequency formed by radiation beats coming directly from object and from output of reference channel. EFFECT: improved reliability of device. 1 dwg
