摘要： A combined optical imaging/display device employs a liquid crystal light valve (LCLV) with a charge coupled device (CCD) input, and a photosensitive CCD or charge injection device (CID) array for receiving an input image and developing a corresponding signal pattern. The signal pattern is applied as an input to the CCD after amplifying it and manipulating it as desired. The CCD and photosensitive array are provided on a common substrate; their cells may be arranged in alternating rows or in separate arrays. The invention is applicable to active vision enhancement goggles.

摘要： Apparatus for compensating for inherent distortions in a modified liquid crystal light valve used in an integrated wavefront sensing and wavefront control system for laser optics. A main wavefront sensing and control system utilizes a liquid crystal light valve selected for response speed but having inherent surface non-linearities. A beam from an auxiliary laser is intermittently applied, while the main laser is blocked, to both the fast response LCLV of the main system and to a slower response LCLV of an associated correction system. The second LCLV system corrects for the non-linearities in the surface of the first LCLV and then maintains the stored correction signal for a decay interval which corresponds to several response times of the main LCLV, thus permitting the main LCLV system to perform fast correction of atmospheric aberrations in the laser beam wavefront unaffected by inherent surface non-linearities.

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 (46) 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) maintain the substrate (40) substantially depleted of such carriers and also reflects the modulated beam back through the liquid crystal.

摘要： A liquid crystal light valve is provided with a microgrid of grooves in the photoconductor surface to divide the photoconductor into high resolution pixels. The liquid crystals fill the grooves to seal them and contribute to a potential barrier at the grooves that prevents lateral charge migration between pixels. In a metal oxide semiconductor (MOS) embodiment an oxide layer extends over the pixels and partially overhangs the grooves. A metal matrix mirror is formed over the insulative layer, and extends into a portion of the grooves to shield the underlying silicon from photoactivation while maintaining an electrical isolation between pixels.

摘要： A semiconductive substrate, such as a silicon wafer, is mounted on a baseplate for inclusion in an optical device such as a liquid crystal light valve. An optical flat presses the top surface of silicon wafer toward the baseplate and against an O-ring seal surrounding a fluid adhesive. The fluid adhesive hydrostatically distributes the force of compression to guarantee optical flatness and self-compensation for the amount fluid adhesive surrounded by the O-ring. The optical flatness of the semiconductor substrate is limited only by the flatness of the optical flat against which it is compressed. Parallel alignment of the optical flat, the substrate and the baseplate is achieved by reflecting a laser beam through the semiconductive substrate and observing the interference fringes therein, while adjusting the relative alignment so as to maximize the distance between fringes.

摘要： An eye protection device 10 comprising a liquid crystal light valve 20 for providing an image of a scene. The light valve images the field of view under observation in a spectral range which matches the human eye. It will automatically reject a laser threat by simply absorbing the energy therefrom in the photoconductive layer thereof. Thus, the invention 10 provides a broad spectrum, zero response time, angle and polarization independent, sensitive eye protection device having a fast recovery time, high extinction coefficient and a high damage threshold. Hence, the invention is expected to be of significant utility to personnel operating in hostile environments.
