    摘要: A spatial light modulator and a lighting system used in, for example, projection displays are provided. The lighting system has a polarizing plate optically disposed in parallel to a light modulating layer of the spatial light modulator, thereby orienting the polarization of readout light beams incident on the spatial light modulator in the same direction to increase the contrast of images projected on a screen. The spatial light modulator is provided with a coupling prism having a side surface opposed to an entrance surface on which the readout light beams are incident. The side surface is so inclined inward as to allow stray light in the coupling prism to go out of the coupling prism without being reflected, thereby eliminating a decrease in contrast of images with a screen caused by the stray light.

    摘要: An image formation apparatus using a recording medium including a scattering-mode light-modulation member which takes an opaque state in response to a heat and takes a transparent state in response to an electric field. The apparatus comprises a heater and an electrode device which are disposed in opposed relation to the recording medium. The heater preheats the recording medium in accordance with a control signal from an external device and the electrode device applies an electric field to the recording medium after the heating, thereby completely erasing an image previously recorded in the recording medium. After the erasure, the recording medium is heated by a thermal head in accordance with an information signal from an external device so as to form a new image in the recording medium.

    摘要: There are provided an image information processing method and an apparatus thereof to process information carried by an electro-magnetic radiation beam by means of a photo-to-photo transducer. An intensity of an image information is adjusted by varying the intensity of an electro-magnetic radiation beam used for reading the information as electro-magnetic radiation beam information, which has been recorded on the transducer as a charge image. The electro-magnetic raidation beam information read out from the transducer is inverted by changing an operating range of a photo-modulation layer which is one of the components of the transducer. Furthermore, the electro-magnetic radiation beam information read out from the transducer is nonlinearly processed.

The optical system supplies optical information to the photoconductive layer, and the pair of electrodes are for generating an electric field therebetween to be applied to the photosensitive layer and the light-modulation layer. Also included in the apparatus for emitting light having a predetermined wavelength, the light being led to the light-modulation layer to generate reflection light therefrom which is modulated in correspondance with the optical information supplied from the optical system to the photoconductive layer. The reflection light is arranged so as to illuminate a photosensitive resin layer, which is in turn denatured or hardened in response to the illumination so as to produce a print plate.

    摘要: There is provided a photosensitive medium for recording a charge latent image, composed of a photo-conductive layer having an electrode and a protective layer at each surface thereof. There is further provided a charge latent image recording method. A photo-conductive layer and a charge holding layer, each having an electrode at a surface thereof, are arranged to face each other through a gap. A predetermined voltage is applied across the photo-conductive layer and the charge holding layer through the electrodes to cause discharge thereacross. At the time, an electro-magnetic wave corresponding to the charge latent image intended to be recorded is emitted to the photo-conductive layer. The impedance of the photo-conductive layer is thus varied to record the charge latent image on the charge holding layer. In the method, the rise time constant of the voltage applied across the electrodes is adjusted to that of the discharge or more, and the potential of the charge latent image is adjusted to a discharge starting voltage or less.
