    摘要: A drive apparatus for an optical element array includes a counter counting clock pulses and being periodically reset at a horizontal scanning period. The counter outputs first and second counter signals out of phase with each other. A latch holds a pixel-corresponding segment of an input image signal. One of clock signals out of phase with each other is selected in response to the pixel-corresponding input-signal segment held by the latch. A first comparator compares the first counter signal and the pixel-corresponding input-signal segment held by the latch, and outputs a first identity signal when the first counter signal and the pixel-corresponding input-signal segment are equal to each other. A second comparator compares the second counter signal and the pixel-corresponding input-signal segment held by the latch, and outputs a second identity signal when the second counter signal and the pixel-corresponding input-signal segment are equal to each other. A drive pulse is generated which starts in synchronism with a start of a horizontal scanning period and which ends in response to the selected clock signal and in response to the first and second identity signals. An optical element in the array is driven in response to the drive pulse.

    摘要: An image processing system for an image display comprising an image data producing device for producing image data corresponding to an image to be displayed and a display device for displaying the image on the basis of the produced image data. The image data producing device divides the image data into a plurality of data sections respectively corresponding to image areas constituting the image so that each of the plurality of data sections is produced as serial data and the plurality of data sections are outputted in parallel. The display device includes a number of pixel elements continuously arranged one-dimensionally or two-dimensionally and equally divided into a plurality of element sections respectively corresponding to the plurality of data sections. The display device is responsive to the image data from the image data producing device so that the plurality of data sections are inputted in parallel to the plurality of element sections, whereby the display device displays the image on a screen on the basis of the plurality of inputted data sections. This arrangement can speedily display a jointless high-grade image in real time.

    摘要: There is provided an optical system for a spatial light modulator. The system comprises a light source for emitting an unpolarized light, a separator for separating a first linearly polarized light having a specified plane of polarization from the unpolarized light and polarizer for rotating the plane of polarization of the first linearly polarized light at a specified angle different from the specified angle to obtain a second linearly polarized light, wherein the second linearly polarized light is adopted as a reading light. Also provided is a method of photomodulation, comprising the steps of separating a light in the region of a specified wavelength from an unpolarized light, separating a first linearly polarized light having a specified plane of polarization from the light and obtaining a second linearly polarized light by rotating the plane of polarization of the first linearly polarized light at a specified angle.

    摘要: There is provided an apparatus for displaying an image on a screen by projecting a reading light from a light source onto a spatial light modulator of reflective type in which the image is written, and projecting a reflected light from the modulator corresponding to the image onto the screen through a projection lens, the modulator, lens and screen being provided so that their optical axes are in agreement on one optical path. The apparatus comprises an optical device provided between the lens and screen for the reading light toward the modulator and passing the reflected light to the screen and a converging element for converging the reading light on the position which is on the optical axis of the lens and located between the lens and screen so that the reading light thus turned becomes a parallel pencil beam which is projected onto the modulator in parallel with the optical axis.

    摘要: A spatial light modulator which includes a light modulation layer which is interposed between two photoconductive layers and laminated to both layers; the two photo conductive layers have charge images written thereon, respectively, by illumination of a writing light carrying optical information; the illumination direction of the writing light to the photoconductive layers are different from each other; and the two photoconductive layers permit the reading light to pass therethrough. When illuminated by a reading light via either of the first or second photoconductive layers, the light modulation layer optically modulates the reading light in accordance with the first and second charge images, under the presence of a voltage applied to the modulator. Thus it reads read out the first information and second information. The first and second photoconductive layers permit the reading light to pass therethrough.
