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.

摘要： Various optical modulation systems and methods are disclosed which are based upon modulating the refractive index of a nipi structure. The refractive index modulation is accomplished by applying a controlled voltage differential across the n-doped and p-doped layers of the structure. Staggered contacts to the layers are formed by conductive elements which extend through the structure. One of the elements establishes ohmic contacts with the n layers, and the other with the p-layers. When implemented as an optical spatial phase modulator, one of the nipi contacts is provided as a grid which divides the structure into a matrix of pixel elements, with the other contact comprising separate wires extending through each pixel. A spatial voltage pattern is applied to the pixel wires to inject charge into their corresponding layers, and thereby modulate the refractive indices of the pixels. This imposes a desired spatial phase modulation onto a readout beam transmitted through the nipi structure. Various guided wave applications are also disclosed in which a beam is transmitted through a nipi structure parallel to the n and p layers. The nipi sturcture is not divided into pixels, but rather has a common voltage differential between its n and p layers. The structure's refractive index is spatially modulated by varying this voltage differential, whereby the spatial voltage modulation is transferred onto the beam.

摘要： A head-mounted display device (10) offers light weight, a low center of gravity, and low moments of inertia about the azimuthal and elevational axes of head movement. The display device (10) employs an angulated beam splitter mirror (16) disposed between a user's (22) eye (20) and an inner combiner surface (18a) of a visor (28). A projector (36) is carried laterally of the user's eye with a low center of gravity and a position close to the horizontal axis of elevational movement of the head. This projector (36) includes an image source (12) and an compact light-weight relay optics module (14) along with a projection fold mirror (30) disposed at eye level and laterally of the beam splitter mirror (16) to project image light to the beam splitter mirror (16). The beam splitter mirror (16) reflects the light onto the inner surface (18a) of the combiner (18) for reflection back through the beam splitter mirror (16) and to the user's eye (20). Alternative embodiments provide for color correction, or for monochrome image projection at even lighter weight. An alternative embodiment provides for both color correction and a weight nearly as light as the monochrome version by use of diffractive lenses in the relay optics module.

摘要： A cascaded adaptive optics system for correction of aberrations in a light beam. The system includes a plurality of spatial light modulators (SLMs) in a cascaded arrangement to provide an adaptive optics system characterized by wide range, rapid response, and high resolution. The spatial light modulators may be identical or have characteristics that are complementary in providing a combined output that advantageously corrects for aberrations. A conventional adaptive optics system such as a deformable mirror may be used as one or more of the SLMKs. Liquid crystal light valves (LCLVs) may be advantageously used as one or more of the SLMs in the invention. A single LCLV may be cascaded with itself in a multiple-pass configuration by means of suitable reflectors.

摘要： Apparatus for performing a division of a dividend intensity array by a divisor intensity array on a pixel-by-pixel basis, to yield a quotient intensity array, wherein optical feedback principles are utilized in conjunction with two spatial radiation modulators, so that analog division is achieved. Specifically, a fraction of the output array of a first spatial radiation modulator is provided as the readout array to a second spatial radiation modulator, whose input is the divisor intensity array. The output array of the second image converter is then added to the dividend array and provided as the input to the first spatial radiation modulator, whereupon the output of the first spatial radiation modulator is the pixel-by-pixel quotient array resulting from division of the dividend array by the divisor array.
