Abstract: A photoconductive-ferroelectric device is employed as an erasable storage medium for recording and reading light patterns. The ferroelectric material may be a bismuth titanate crystal and its polarization pattern (corresponding to the recorded light pattern) is read out by directing linearly polarized light at the ab-face of the crystal, at an angle to the c-axis of the crystal and preferably perpendicular to the b-axis of the crystal. With proper choice of the direction of linear polarization, the incident light is phase delayed different amounts in the differently polarized regions of the crystal and this difference in phase may be detected and employed as the basis for reconstructing the light pattern. Operation in this way is found to provide substantially greater readout efficiency than has been available heretofore.

Abstract: The sharp change in optical properties of ferroelectric and other materials at or near their transition temperature (in the case of ferroelectric material, this may be their ferroelectricparaelectric transition temperature, Curie point) is made use of in light deflectors, light valves and the like. The material is heat biased as, for example, by the application of an alternating voltage of an amplitude sufficient to produce the TANDEL or an analogous effect, to a value close to its transition-temperature. An electrical pulse may then be applied to the material for causing sufficient additional heating to raise the temperature of the material to a different value such as one above the transition temperature. The change in optical properties which results may be employed to deflect or otherwise affect a beam of light applied to the material.

Abstract: A LIGHT DEFLECTOR IS DISCLOSED WHICH INCLUDES AN INPUT FABRY-PEROT TYPE RESANOTOR, AND AN OUTPUT FABRY-PEROT TYPE RESONATOR. THE TWO RESONATORS ARE SEPARATED BY A TRANSPARENT WEDGE HAVING AN ANGLE A/2. A SOURCE OF A LASER BEAM OF MONOCHROMATIC COHERENT LIGHT IS DIRECTED TO THE INPUT RESONATOR AT AN ANGLE OF INCIDENCE $ (RELATIVE TO A NORMAL REFERENCE LINE) AT WHICH THE RESONATOR EXHIBITS A TRANSMISSION PEAK, SO THAT A BEAM OF LIGHT IS TRANSMITTED INTO AND THROUGH THE TRANSPARENT WEDGE TO THE OUTPUT RESONATOR. MEANS ARE PROVIDED TO VARY A PHYSICAL PARAM-

ETER IN THE LIGHT PATH THROUGH THE SECOND RESONATOR IN AMOUNTS TO CAUSE A BEAM OF LIGHT TO EMERGE FROM THE OUTPUT RESONATOR AT ANY ONE OF MANY ANGLES, RELATIVE TO SAID REFERENCE LINE, APPROXIMATELY EQUAL TO 0 PLUS AN INTEGRAL MULTIPLE INCLUDING ZERO OF A. THE PARAMETER VARIED MAY BE THE PHASE DELAY IN THE OUTPUT RESONATOR, OR A PHSYCIAL SPACING OF RESONATOR SURFACES.
