    摘要： There is provided a low-vision aid device, including a scene-display imager producing a signal pattern composed of an array of pixels, a near IR illuminator for illuminating the retina of the eye with radiation for eye tracking, to be reflected from the retina of the eye, an eye-retina tracking imager, and an image transceiver device capable of providing both functions of eye imaging as well as image display by selectively rotating the polarization of individual pixels of the array of pixels of the signal pattern, to allow the transference of selected portions of the signal pattern to reach the retina of the eye.

    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： A visible to infrared dynamic image converter light valve includes two liquid crystal layers disposed on opposite sides of a photoconductive substrate. The two liquid crystal layers spatially modulate an incident infrared beam by polarization rotation. A voltage is applied across the two liquid crystal layers, with the layers being responsive to the applied voltage, to vary the polarization rotation. The photoconductive layer receives and absorbs a visible wavelength image and spatially modulates the voltage across the two liquid crystal layers responsively to image intensity spatially to vary the polarization rotation. A mirror reflects the incident infrared beam back through the first and second layers such that the beam passes through the liquid crystal layers twice and is polarization rotated in proportion to the visible wavelength image. A wire grid polarizer converts the polarization rotation of the infrared beam to output intensity modulation to produce an infrared image.

    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.
