摘要： The invention relates to systems and methods for optical Fourier processing and logic operations based on the discovery that the photoinduced anisotropy of photochromic materials such as bacteriorhodopsin, organic fulgides, azo and fluorescent dyes, phycobiliproteins, rhodopsins, and their analogs, is dependent on the intensity of a polarized actinic beam that illuminates the material and the intensity profile of one or more input beams. This intensity dependence can be used to implement a simple, real-time, self-adaptive optical processing, i.e., spatial filtering, system for Fourier processing of optical input images. This optical processing system can be used to process a wide variety of optical input images, from projected still images to live motion picture images.

摘要： An apparatus for deflecting light of the present invention comprises: (a) at least one pair of transference electrodes arranged facing one another; (b) a drive circuit which applies a voltage among the transference electrodes; and (c) a liquid crystal which is inserted among the transference electrodes, and whose parallel stripes that function as a diffraction grating when the voltage is applied among the transference electrodes are produced at a pitch corresponding to the applied voltage. The light can be scanned if a diffracted light by the apparatus for deflecting light is converted into a scanning light and a voltage value is changed temporally to apply the voltage among the transference electrodes. In a device for reading information, the scanning light is reflected in a bar code and the reflected light is detected by an apparatus for detecting light. In a device for stereoscopic display of the present invention, the apparatus for deflecting light is used as beam deflection means for deflecting the light beamed from a picture element which organizes the pictures of the picture display means.

摘要： A hologram of a virtual object or an object which actually exists is formed and a solid image is displayed. 3-dimensional information of the object to be displayed is divided into regions in the depth direction. Depth images are formed as 2-dimensional images where are seen from a plurality of points which are obtained by finely dividing the hologram forming surface for every region. A phase distribution at the hologram forming surface is calculated from the depth images and displayed on a liquid crystal display or the like as an electronic hologram. A reference light is irradiated onto the display and is converted into an optical wave front, thereby displaying a solid image. When forming a hologram recording medium, a zone image corresponding to each of the finely divided exposure regions of a dry plate is exposed multiple times.

摘要： A diffraction light modulated by a plane type phase distribution display device is deflected by an image formation optical system and is formed as an image onto a cylindrical screen surface and is diffused in the vertical direction by a unidirectional light diffusing section such as a lenticular lens or the like, so that a stereoscopic image can be seen. As a phase distribution display device, a liquid crystal device having pixels on the order of the wavelength in the circumferential direction and having coarse pixels in the radial direction is used. Thus, it is equivalent to that the phase distribution display device is located on the cylindrical surface. A cylindrical stereoscopic display can be performed by using the plane phase distribution display device.

摘要： An apparatus for processing a hole with a rounded edge includes a punch having a rounded shape formed at a base portion of a cutting tip, and a die supporting a peripheral edge of a pierced hole formed through piercing by the cutting tip of the punch with a pressure receiving surface perpendicular to a punch axis. By driving the punch to make a single stroke motion, a hole is pierced in a work piece by the cutting tip of the punch to form the pierced hole and the rounded shape of the cutting tip is transferred onto a ridge portion on the side of a design surface of the pierced hole. This permits efficient processing of holes with a rounded edge. In addition, by supporting the peripheral edge of the pierced hole with the pressure receiving surface, a uniform and highly accurate rounded shape can be formed on the ridge portion of the pierced hole.

摘要： A high-resolution light-beam scanning apparatus utilizing only mass-producible holograms instead of utilizing auxiliary optical systems such as optical lenses or a mirror having curvature, and capable of compensating for disadvantages including scanning beam thickening and variation, failure of a rotatable hologram to rotate at a constant velocity, displacement of a scanning beam position in the scanning direction and the cross scanning direction due to a mode hop of a wavelength of a semiconductor laser, and deviation of a base of rotatable hologram from a parallel state. These disadvantages are detrimental to efforts for increasing the resolution of a hologram scanner and lowering the cost thereof. The light beam scanning apparatus includes at least two holograms with an optical path length difference .DELTA..PHI. along a scanning beam light flux. The path length is measured from a light source to a scanning surface in the first hologram, and is represented by .DELTA..PHI.
