A rewritable hologram memory carries a plurality of stored images as holograms so that the holograms are overlapped with each other, the rewritable hologram memory being written with image information when illuminated by a recording optical beam. An image reproducing part is supplied with the input image information, and produces reproduced image information from the rewritable hologram memory. A hologram synthesizing part synthesizes a synthetic hologram in response to the reproduced image information. A hologram recording part records the synthetic hologram in the rewritable hologram memory through the recording optical beam.

摘要： A parallel image processing apparatus includes (1) a light diffusing layer, (2) a photoelectric conversion layer which receives diffused light from the diffusion layer, and (3) an edge detection layer which receives signals from conversion elements in the conversion layer, and generates edge information which defines the edge of object(s) imaged on the light diffusing layer. The conversion layer includes pairs of conversion elements, the pairs having a center element and a peripheral element surrounding it. Signals from one or more center elements are summed, the sum being differentially amplified with a sum of signals from one or more peripheral elements to arrive at an edge signal. Edge signals may be used to differentiate among characters, pictures or photographs, and a blank images.

摘要： The present focusing method is used in a focus detecting apparatus comprising an objective lens, means for entering a luminous flux for focus detection into a target object from a position inconsistent with an optical axis of the objective lens through at least the objective lens, a condenser lens for converging the luminous flux after it is reflected by the target object and again passes through the objective lens, two two-division sensors disposed with the same optical inclination in front of and behind a position where the reflected luminous flux is converged by the condenser lens when a focus of the objective lens is adjusted to the surface of the target object, and a signal processing circuit for performing operational processing of signals from the two two-division sensors. The focus detecting apparatus detects whether the focus of the objective lens is adjusted to the surface of the target object. When focusing is performed with this apparatus, the target object is moved while the focus position is followed after the detection of the focus position, focus detection is performed many times and the detected signal values are averaged, and the resultant average value is used to drive the objective lens. This series of operations is repeated, and then the focus position is fixed.

摘要： An optical packet header identifier having a simplified configuration and being superior in reliability, stability, and economical efficiency, an optical router incorporating the identifier therein, and a routing method using the optical router are provided. The optical packet header identifier includes an optical waveguide, optical focusing elements, and a photo receiver. Tilted gratings for diffracting an incident optical beam and emitting the beams as diffracted optical beams to the outside of the waveguide are formed within the optical waveguide. The tilted gratings are not formed uniformly in a longitudinal direction of a core of the optical waveguide, but are arranged at intervals. The length of a portion containing a set of gratings and the length of a portion containing no gratings can be defined in increments of length “L”. “L” equals to the spatial length which 1 bit in an optical signal occupies.

摘要： In laser beam scanning by a rotating polygonal mirror, a hologram scanner, etc., a cylindrical lens having a refractive power in a sub-scanning direction is introduced to place the beam deflecting surface and the scanning surface in a geometrical-optically conjugative relation, in order to prevent occurrence of a deviation in position of scanning line due to a deviation of the beam deflecting surface. However, in a Gauss beam such as a laser beam, a beam waist is not produced in a geometrical-optical conjugate point. This relation is utilized to select optical elements whereby apparatus may be miniaturized and the size of the beam spot may be adjusted.
