摘要： A reflective matrix mirror visible to infrared converter light valve (5) includes a liquid crystal medium (60) for spatially modulating an incident infrared beam by polarization rotation, a photosubstrate (30) for receiving an incident visible wavelength image (115) and for controlling the polarization rotation of the liquid crystal medium (60) responsively to the visible image (115), and a reflective matrix mirror (40). The reflective matrix mirror (40) is positioned between the liquid crystal medium (60) and the photosubstrate (30) and reflects the incident infrared beam (125) back through the liquid crystal medium (60) such that the infrared beam (125) passes through the liquid crystal medium twice and is polarization rotated responsively to the visible wavelength image (115). A polarizer (90) positioned exteriorly of the liquid crystal medium (60) converts the polarization rotation of the infrared beam (125) into output intensity modulation to produce an infrared image (130). The reflective matrix mirror (40) comprises an M x N array of infrared reflective islands comprising metallic or semiconductor/metallic compounds.

摘要： A double Schottky diode light valve (5) includes a liquid crystal (80) for locally modulating a beam (120) by polarization rotation to produce a modulated beam (121), and a photoconductor (40) located adjacent the liquid crystal (80) for receiving and absorbing a second beam (110). The photoconductor (40) controls the polarization responsively to the optical content of the second beam (110). The photoconductor (40) includes a semiconductor substrate and a pair of Schottky diodes (60/40, 30/40) disposed on opposing sides of the substrate. The absorption of the second beam (110) by the substrate (40) produces photogenerated majority carriers. The pair of Schottky diodes (60/40, 30/40) maintains the substrate (40) substantially depleted of such carriers and also reflects the modulated beam back through the liquid crystal.

摘要： The invention provides optical modulation devices and displays of the DHFLC type having a high contrast. Said modulation devices comprise a first substrate and a second substrate which are positioned substantially parallel to each other and which are provided, on their facing surfaces, with, in succession, an electrode layer and an orientation layer. This advantageous effect is achieved by using different orientation layers, the surface energy of the orientation layer of the first substrate being different from the surface energy of the orientation layer of the second substrate, said difference in surface energy being at least 5 mN/m. The orientation layer having the high surface energy is preferably made from rubbed polyimide, and the orientation layer having the low surface energy is preferably made from unrubbed polyorganosilsesquioxane. The optically active layer of the modulation devices in accordance with the invention exhibits a "tilted-bookshelf" structure.

摘要： A single-Schottky liquid crystal is disclosed in which a series of Schottky contacts are made on one side of a photoconductor substrate by a metal matrix mirror, with a doped semiconductor back contact electrode on the other side of the substrate. The light valve offers several operational advantages over MOS devices, and is easier to fabricate than double-Schottky light valves. It can be operated either in an AC mode or, by doping the liquid crystal ions, in a DC mode.

摘要： The eyes (12) of vehicle's (18) occupants are shaded from the direct or reflected rays of the sun (14) shining through a transparent windshield (16). The system includes a normally transparent envelope (20) which is adjacent to the windshield (16). A layer of normally transparent activatable liquid crystal material, which is adapted to have its light transmissive characteristics selectively changed in response to an electric field, is carried by the sheet. A device (42) for determining the position of the sun sends signals to communicate the position of the sun (14) relative to the windshield (16). In response to such signals, an electric field is applied to selected portions (32) of the normally transparent activatable liquid crystal material to activate and change the light transmissive characteristics of those portions, with the result that the direct or reflected rays from the sun (14) can be selectively shaded from the eyes (12) of occupants within the vehicle (18).

摘要： A method of operating a liquid crystal light valve having a photoconductor and a liquid crystal involves selecting a photoconductor with an appropriate bandgap and an input light having a limited frequency range with a center frequency matching a bandgap of the photoconductor. This results in the light being more uniformly absorbed through the bulk of the photoconductor and the light blocking layer or the light blocking layer and the mirror can be eliminated. The photoconductor can be optimized for sensitivity and short carrier lifetimes necessary for high frame rates.

摘要： A pulsed readout technique is described for liquid crystal light valves which eliminates the problem of readout beam leakage through the light valve mirror. The readout beam is pulsed on only when the light valve's semiconductor layer is out of a depletion state. This can occur during an accumulation state or, in certain applications, during a specially inserted quiescent period in the light valve voltage cycle. The invention is applicable to light valves with various types of modulating inputs, and can be used with either dielectric or metal matrix mirrors.
