PROCESS OF RECONSTRUCTION OF IMAGE BY PLANAR SCREEN Russian patent published in 2000 - IPC

FIELD: optoelectronic information equipment. SUBSTANCE: process includes injection of luminous fluxes from N planar waveguides into layer of ferroelectric liquid crystal. Each of N polycolor luminous fluxes transformed by converter is injected into first planar waveguide without jacket, is propagated over it with the aid of total internal reflection created by lower and side faces of groove of matrix where waveguide is placed and by upper face formed by layer of liquid crystal. Voltage forming electric field with direction perpendicular to direction of propagation of luminous flux is supplied to upper and lower electrodes to bring luminous flux out of planar waveguide. Luminous flux from layer of liquid crystal is injected into cylindrical waveguides without jacket through side faces directed perpendicular to direction of propagation of luminous flux. Refractive index of cylindrical waveguides that ensures total withdrawal of luminous flux through layer of optical adhesive and protecting plate into open space is chosen. EFFECT: enhanced efficiency and resolution of reconstructed image. 10 dwg
