  • Patent number: 5801800
    Abstract: A visual display system, composed of an array of light emitting devices, forming an image source, a phase spatial light modulator scanner, driver/control circuitry and an optical magnification system. The display system being enclosed within a housing, thereby forming an optical magnifier. The phase spatial light modulator scanner is operative in either a transmissive mode or a reflective mode. In operation, an external stimulus, such as a voltage, is applied to the scanner, thereby changing the phase of light emitted therethrough. The scanning action enhances display resolution of the generated resultant image without an increase in the number of pixels of the image source. The phase spatial light modulator scanner operates by scanning sub-pixels, pixel groups, and/or sub-arrays of the image source.

  • Patent number: 5784141
    Abstract: A phase spatial light modulator composed of a liquid crystal cell having molecular orientation recorded during the fabrication process as a direct result of a photochemical reaction exerted upon the liquid crystal material, a mechanically-induced change of a liquid crystal alignment layer, or by varying a plurality of polymer materials that compose the liquid crystal alignment layer, thereby affecting the liquid crystal material contained within the cell. The modulator, or scanner, thereby capable of altering the phase, thus steering light passing therethrough. During operation, the liquid crystal molecules deflect the light beam passing therethrough based on their orientation as recorded during fabrication when the applied voltage is "OFF" or in an altered state when the applied voltage is "ON".

  • Patent number: 5777706
    Abstract: A phase spatial light modulator composed of a first liquid crystal cell and one or more additional liquid crystal cells. Each of the liquid crystal cells is positioned so that their extraordinary optical axis (N.sub.e) lies orthogonal to the next liquid crystal cell, and the group of cells is positioned along the optical axis of light emitted by an image source. The modulator, or scanner, thereby capable of steering substantially 100% of unpolarized light therethrough. The modulator intended for use within a display system additionally composed of an image source, driver/control circuitry and an optical magnification system. In operation, an external stimulus is applied, such as a voltage supplied by an external power source, thereby spatially changing the phase of light emitted therethrough. The scanning action enhances display resolution of the generated resultant image without an increase in the number of pixels of the image source.

  • Patent number: 5764329
    Abstract: A phase spatial light modulator composed of a liquid crystal cell and a reflective element. The modulator capable of receiving and modulating substantially 100% of unpolarized light impinging thereupon. The modulator intended for use within an electro-optical system additionally composed of a light source, driver/control circuitry and an optional optical magnification system. In operation, an external stimulus is applied, such as a voltage supplied by an external power source, thereby changing the phase of light emitted therethrough, generating two beams of light traveling in different directions. The first beam of light impinges upon the reflective element and is reflected to travel in the same directional path as the second beam of light.

  • Patent number: 5751471
    Abstract: A switchable lens includes first and second optically transparent substrates, a first electrically conductive, optically transparent contact film positioned on a surface of the first optically transparent substrate, a second electrically conductive, optically transparent contact film positioned on a surface of the second optically transparent substrate, and phase modulating material sandwiched between the first and second electrically conductive, optically transparent contact films. The phase modulating material has a lens function stored therein which is temporarily erasable by a potential applied between the first and second electrically conductive, optically transparent contact films, the phase modulating material thereby being capable of modulating light passing therethrough.
