摘要： A method for driving a twisted nematic type liquid crystal shutter, the liquid crystal shutter having a pair of transparent substrates held opposite to each other; a pair of patterned transparent electrodes each formed on the planes of the transparent substrates and arranged opposite to each other so that the overlapping parts of the patterns form display pixels; a pair of aligning film each formed on the pattern of the transparent electrode and on the plane; a liquid crystal material contained in a space between the transparent substrates; and a pair of transmission type polarizers each arranged on the outside plane of the transparent substrate which is counter to the plane on which the patterned transparent electrode is formed, comprising the steps of: applying an electric voltage to establish static or multiplex driving to the transparent electrodes so as to prevent the transmission of incident light when no image signal is received from an external apparatus; and preventing the application of the electric voltage to transparent electrodes which relate to the pixels selected by the image signal so as to permit the transmission incident light when the image signal is received from the external apparatus.

摘要： An optical wavelength converting apparatus comprises an optical wavelength converting device, which is constituted of a crystal of a nonlinear optical material and converts a wavelength of an incident fundamental wave into a different wavelength, a holder, which is constituted of a metal and to which the optical wavelength converting device is adhered and secured, and a device for adjusting the temperature of the region containing the optical wavelength converting device. The optical wavelength converting device is secured to the holder by adhering only the surface of the optical wavelength converting device to the holder, which surface is normal to the direction of a crystallographic axis that has a coefficient of thermal expansion most different from the coefficient of thermal expansion of the metal constituting the holder among the coefficients of thermal expansion of the crystallographic axes of the optical wavelength converting device. The optical wavelength converting device is thus reliably secured to the holder and prevented from breaking or being distorted due to a change in environmental temperature, and the accuracy, with which the temperature of the optical wavelength converting device is adjusted, is kept high.

摘要： A light beam scanning system comprises a stack of a wave guide layer and an adjacent layer normally exhibiting a refractive index smaller than that of the wave guide layer, the wave guide layer and/or the adjacent layer being made of a material whose refractive index changes by the application of energy. Many energy application devices are positioned at the wave guide layer and/or the adjacent layer along an optical path of wave guided inside of the wave guide layer. Dielectric gratings are positioned on the adjacent layer so as to correspond to sections where energy is applied. A drive circuit is provided for sequentially and selectively energizing the energy application devices, and changing the refractive index of the wave guide layer and/or the adjacent layer so that the guided wave is radiated out of the stack by interaction with the dielectric gratings at the sections where energy is applied.

摘要： An image is formed in a color photosensitive material through scanning exposure by using at least one semiconductor laser excited solid laser including a semiconductor laser, a non-linear optical element and means for controlling the temperature thereof as a light source for producing a laser beam. The laser beam is modulated by an external modulator in accordance with the image to be formed. Among the combinations of photosensitive layers and laser beams, at least two laser beam light sources are such that a laser beam has a wavelength falling within .+-.20 nm from the maximum wavelength in the spectral sensitivity distribution of the corresponding photosensitive layer. Each photosensitive layer has a spectral sensitivity distribution with a peak width of up to 40 nm. The method enables to form an image in a conventional silver halide photosensitive material having spectral sensitivity in the visible region using a cost effective light source, the resulting image having color generated to a satisfactory density, free of a density variation, and hence of high quality.
