    摘要： A system for producing spatially modulated monochrome or color light having gray scale includes an active matrix liquid crystal spatial light modulator having light modulating means including (i) a layer of ferroelectric liquid crystal material which is designed to switch between ON and OFF states and (ii) active matrix means including VLSI circuitry for dividing the layer of liquid crystal material into an array of individual liquid crystal pixels and for causing each of the pixels of liquid crystal material to modulate light individually by switching between the ON and OFF states in a way that depends upon the data which the VLSI circuitry is written. The system also includes illumination means having a light source for directing light from the source into the pixel-divided layer of ferroelectric liquid crystal material in a specific way. And finally, the system includes means for writing the VLSI circuitry with preselected data in accordance with a particular data ordering scheme such that the circuitry, in response to the written data, causes the pixels of liquid crystal material to individually switch between their ON and OFF states and therefore modulate light from the source in a way which, depending upon the data, produces a specific overall pattern of gray scale light.

    摘要： An optic displacement sensor includes first and second optic circuits which optic circuits include di-directional means for a light supply path to and a light return path from a light reflecting surface means. The first optic circuit is a reference signal circuit, and the second optic circuit is a measuring signal circuit. Means are provided for directing light into the light supply paths for the pair of optic circuits, and means are provided whereby the light from the light supply paths of the pair of optic circuits is received by light reflecting means and at least partially reflected into the light return paths where it is detected. Further, the sensor includes means for adjusting the detected signal from one of the light return paths with respect to the detected light from the other light return path.

    摘要： A multi-state light modulating system having grayscale based on a series of time intervals includes an arrangement that establishes the duration of each time interval such that the time intervals in the series have progressively varying duration. The arrangement also determines a drive signal for each time interval that causes the light modulator to assume a specific light modulating state. The arrangement also causes the light modulator to produce a desired time-averaged light level over the series of time intervals by in part driving the light modulator using the drive signal that corresponds to a particular time interval for a duration that is longer than the duration of the time interval. The arrangement also or alternatively arranges the series of time intervals such that the light modulator is in the same state immediately prior to the particular time interval as the light modulator is in immediately after the time interval.

    摘要： A system for producing modulated light is disclosed. The system comprises a spatial light modulator including a light modulating medium switchable between different states so as to act on light in ways which form overall patterns of modulated light. The system also includes an arrangement for switching the modulating medium between the different states in a controlled way and an illumination arrangement for producing a source of light. The system further includes an optics arrangement for directing light from the source of light into the spatial light modulator and for directing light from the spatial light modulator through a predetermined source imaging area. The optics arrangement cooperates with the illumination arrangement and the spatial light modulator so as to produce a real image of the source of light within the source imaging area such that an individual is able to view a virtual image of the overall patterns of modulated light from the source imaging area. A variety of novel optics arrangements are disclosed including specific combinations of different light sources, diffusing plates, polarizers, beam splitters, analyzers, lenses, mirrors, and holographic optical elements which allow the overall optical arrangement to be miniaturized to the same degree and in coordination with the spatial light modulator. The different light sources include using a plurality of light sources, such as LEDs, to form an array of light sources, each of the light sources providing light to a corresponding portion of the spatial light modulator.

    摘要： A display system for acting on light entering the system includes a reflective ferroelectric liquid crystal spatial light modulator and a polarizer arrangement. The polarizer arrangement includes a polarizer for polarizing the light entering the system and directing the polarized light into the spatial light modulator along an optical path having an optical path axis. The reflective spatial light modulator acts on the polarized light to produce an optical output that is directed from the spatial light modulator back into the polarizing arrangement along substantially the same optical path axis that the polarized light is directed into the spatial light modulator. The polarizing arrangement also includes an analyzer configured to receive and analyze the optical output of the spatial light modulator and to direct the analyzed optical output out of the system. A compensator is positioned in the optical path between the polarizer of the polarizing arrangement and the spatial light modulator and in the optical path between the spatial light modulator and the analyzer. The compensator includes a layer of ferroelectric liquid crystal light modulating medium switchable between a first compensator state and a second compensator state. The compensator is configured such that the compensator inverts the optical output of the spatial light modulator when the compensator is switched to the second state. The layer of ferroelectric liquid crystal light modulating medium of the compensator and the spatial light modulator having retardances that are substantially different than one another.
