摘要： Reflective spatial light modulator array is described incorporating liquid crystal devices, mirrors, a semiconductor substrate, electrical circuits, and a reflector/absorber layer for blocking light. The invention overcomes the problem of shielding light from semiconductor devices, high optical throughput and contrast, pixel storage capacitance to hold the voltage across the liquid crystal device and precise control of the liquid crystal device thickness without spacers obscuring the mirrors.

摘要： An optical system for a projection display employing three reflective spatial light modulations (SLM's) is described. Two or the three SLM imaging paths employ typical image combining and projection optical techniques. However, the third SLM imaging path employs a relay lens to produce an intermediate image of the SLM which is subsequently combined with the other two images. Each color component is directed onto one of three SLM's, each through its own polarizing beamsplitter (PBS) cube. In two of the three SLM's, image forming light is reflected from each SLM and passes through its respective PBS, and the two colors are then recombined using a dichroic coating. A lens then images the two-color image, and projects it onto a screens. The third SLM traverses a completely separate path. In this case, the image forming light reflected by the SLM and passing through the PBS is first imaged by a relay lens of approximately unity magnification to produce an intermediate image plane. This intermediate image (of the third colors SLM) is then recombined with the first two color images using PBS or a dichroic coating. The recombination is accomplished in a manner that ensures that the three color images are located at the back focal distance of the projection lens.

摘要： This disclosure provides an optical scanner for transforming an optical image into electrical signals.Through practice of this disclosure an optical image is projected onto a surface of a photosensitive semiconductor body wherein there is established a charge distribution or perturbation or pattern which reflects the variations in optical intensity of the optical image. Through the parametric interaction of simultaneously applied electric field and acoustic wave to each respective portion of the electrical charge pattern on the photosensitive semiconductor surface, there is obtained a backward acoustic wave which is directed toward the source of the initiating acoustic wave. In particular, the acoustic wave in the acoustic medium may be either a surface acoustic wave (SAW) or a bulk acoustic wave. Where the surface acoustic wave is utilized, the acoustic medium may be commensurately thin. The acoustic medium must be piezoelectric for it is the interaction of the electric field of the acoustic wave with the applied electric field via the charge pattern which achieves the parametric interaction. Through the "holographic" electric field echo effect, an optical scanner may be achieved for the practice of this disclosure by storage of a charge pattern related to the optical image.

摘要： A twisted nematic liquid crystal (TNLC) cell used in reflective spatial light modulators (SLMs) of displays is disclosed. The TNLC cell includes front and rear substrates, and a TNLC material having a thickness d and a left-handed or right-handed twist angle .phi.. The TNLC material is sandwiched between the front and rear substrates, and the twist angle .phi. is approximately from 46.degree. to 62.degree.. A direction of directors of the TNLC material located nearest the front substrate forms an initial angle .beta. with a direction of linearly polarized light incident thereon. The initial angle .beta. is approximately from -6.degree. to 60.degree.. A birefringence .DELTA.n of the TNLC material times the thickness d is between approximately 0.7.lambda. to 1.25.lambda., where .lambda. is a wavelength of light incident on the front substrate.

摘要： A reflective spatial light modulator array is described incorporating liquid crystal devices, mirrors, a semiconductor substrate, electrical circuits, and a light blocking layer. The light blocking layer can be a reflector/absorber layer containing titanium. The light blocking layer can be a layer resulting in attenuation of incident light below a certain level at the semiconductor substrate. The invention overcomes the problem of shielding light from semiconductor devices, high optical throughput and contrast, pixel storage capacitance to hold the voltage across the liquid crystal device and precise control of the liquid crystal device thickness without spacers obscuring the mirrors.

摘要： A spatial light modulator designed to use a minimum area on the surface of a silicon substrate. This invention comprises a silicon substrate on a back plate with a glass cover that is used to seal liquid crystal between the glass cover and the silicon substrate. Most importantly, the glue seal formed to contain the liquid crystal material is between the cover glass plate and the Si substrate on only one side and the back plate on the remaining three sides. This structure allows a smaller semiconductor substrate to be used.
