Abstract

The invention refers to the field of registration of optical information including the holographic one and may be used in the holography, cinematography, micro- and optic electronics, computer engineering. Summary of the invention consists in, that in the carrier containing a dielectric substrate on which there are placed in sequence the first electrode, photo-injection substrate, registration substrate of the chalcogenide vitreous semi-conductor and the second electrode, the photo-injection substrate is fabricated of the mono-crystalline germanium of the n-type conductivity and the relation of the registration substrate conductivity sr during illumination to the photo-injection substrate conductivity in darkness s0 is 0,001 ú s r/s0 ú 0,05 and the registration substrate thickness L is given in the limits of 2 . 10-7 ú L ú 8.10-7 m. The technical result consists in increasing the carrier photosensibility and in diffraction effectiveness of the information registered on the carrier. Claims: 1 Fig.: 1
