| Number | Title | Issue Date |
| 4830448 | Light modulator and wave guide device A light modulator comprises a stack of a wave guide layer and an adjacent layer normally exhibiting a refractive index smaller than that of the wave guide layer, at least one of these layers being formed of a material whose refractive index changes by app... | 05/16/1989 |
| 4807976 | Light valve system and method with pulsed readout 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 depletio... | 02/28/1989 |
| 4796982 | Optical valve An optical switch comprising a transparent prism having a light input surface and a light output surface, and a reflective control layer having a refractive index higher than that of said prism and a thickness not smaller than the wavelength of the light ... | 01/10/1989 |
| 4789228 | Electrically controlled optical switching device The present invention concerns a device where the commutation of a luminous beam is ensured by the electrically controlled presence or absence, on the path of the beam, of a fluid causing said beam to be transmitted or reflected. The invention provides fo... | 12/06/1988 |
| 4749262 | Metal film light modulator An improved device for modulating the intensity of a light beam is described which comprises a first isoceles optical prism; a first dielectric layer, a thin metallic layer, and a second dielectric layer substantially identical in composition and thicknes... | 06/07/1988 |
| 4669831 | Total internal reflection modulator/deflector A total internal reflection modulator/deflector assembly for use with a focused beam of polarized incident laser light. The application of a low direct current voltage (e.g., less than 50 volts) to a pair of identical stacked crystals exhibiting the Pocke... | 06/02/1987 |
| 4561728 | Electrooptical comparators Apparatus receives light (11) in an input direction (12) and controls the directions in which portions of it travel through adjacent regions (13,14,15,16) in a waveguide (19) to emerge (at 17) in an output direction (18) with intensity responsive to a plu... | 12/31/1985 |
| 4493085 | Agile beam laser A laser system for providing a rapidly steerable laser output beam. The laser system includes a phase conjugate reflector, laser gain medium and its associated pump source, an output coupling device, and an optical element which selectably controls the tr... | 01/08/1985 |
| 4380373 | Conformable proximity coupled electro-optic devices The electrodes of a electro-optic device having a flexible electrode bearing member, such as a silicon integrated circuit, are re-contoured as required to generally conform to the mating surface of the electro-optic element by resiliently biasing the elec... | 04/19/1983 |
| 4376568 | Thick film line modulator A thick film line modulator/scanner (50) for use in an electro-optic line printer (14). A light valve utilizes a thin electro-optic layer (212) with the index of refraction of the layer being higher than the neighboring material so that the light can be g... | 03/15/1983 |
| 4218302 | Electrophoretic display devices An electrophoretic display device comprises a cell in which a colloidal suspension of pigment particles is contained between associated electrodes and means are provided for the establishment of a potential between the electrodes for the selective transpo... | 08/19/1980 |
| 4196977 | Electro-optic modulator/deflector An electro-optical modulator/deflector including electro-optical material and an electrode pattern arranged in response to a voltage supply to provide an electric field in the material to influence the deflection of a light beam at the moment of total int... | 04/08/1980 |
| 4090779 | Light beam position control system The system herein includes a unique array of light beam reflecting surfaces and reflection control means for effecting changes in the position of a light beam along the scan-line output surface of the system with a much higher degree of sensitivity than i... | 05/23/1978 |
