摘要： An electric photograph system for improving non-linearities of an exposing light intensity and an operating current at a low exposing level when performing analog printing operation. A range (saturable absorber) having a saturable absorbing characteristic is provided in a part of an optical path including a semiconductor laser as light source to improve the non-linearity of the operating current when the light intensity is weak. The saturable absorber may be made in the form of a non current injected area provided in a part of the semiconductor laser as the light source or a thin film layer provided partly in films coated on a facet of the semiconductor laser. Due to the provision of the saturable absorber, the light output power characteristic can exhibit its linearity in its low optical power range, the size of a printing dot can be arithmetically changed, and thus fine laser printing can be realized.

摘要： An optical disc drive using either one of a first disc (e.g., DVD) and a second disc (e.g., CD), is provided with a first laser diode that emits a shorter wavelength beam, a second laser diode that emits a longer wavelength beam, an objective lens, and a driving unit that holds and rotates the optical disc. The optical axis of the objective lens is inclined relative to a normal to the optical disc. The first laser diode is located at a first position so that the coma, which is caused when the first laser beam is converged on a data recording surface of the first disc, is minimized, and the second laser diode is located at a second position so that the coma, which is caused when the second laser beam is converged on a data recording surface of the second disc, is minimized.

摘要： High-grade three-dimensional images can be observed without a bright image of an exit end of an image projector superposed on the three-dimensional images. In a method of reproducing three-dimensional images by a three-dimensional image-reproducing device provided with an image projector and a directional reflective screen for collecting light from the image projector toward a specific position in a horizontal direction and for diffusing the light in a vertical direction, the directional reflective screen and the image projector are positioned with respect to the observer observing the three-dimensional images such that the observer is outside a region traversed by a portion of light rays which enter the directional reflective screen from the image projector, then are reflected by a surface of the directional reflective screen incapable of contributing to the reproduction of the three-dimensional images, and form a mirror image or a conjugate image of the image projector.

摘要： In an optical head, light from a semiconductor laser is directed through a condensing optical system with a condensing lens onto an optical information recording medium through a transparent substrate in the form of a light spot. A unit for producing a light spot position control signal and a unit able to move the light spot, which supports the objective lens for movement, position the light spot on an information track. Light reflected from the optical information recording medium is directed through a polarized light branching element to a photo detector. Also mounted for movement with the objective lens are a polarization conversion element, arranged between the optical information recording medium and the polarized light branching element in order to change the polarization state of light incident to the optical information recording medium and reflected therefrom and a polarization diffraction grating, the diffraction efficiency of which changes depending on the change in the polarization state of the incident light and the reflected light caused by the polarization conversion element. The light spot control signal is detected from both reflected light diffracted through the polarization diffraction grating and non-diffracted reflected light contained in the light which passes through the polarized light branching element.

摘要： A reflective liquid crystal display apparatus has a liquid crystal display part composed of at least a liquid crystal layer and a pair of polarizers holding the liquid crystal layer therebetween, for display of bright and dark states in a mode of transmitting and shielding external light in a direction approximately normal to a display plane, and a reflecting part for reflecting the external light which has been transmitted through the liquid crystal display part. The liquid crystal display part has a property where it can transmit external light in a designated direction other than in a direction approximately normal to the display plane even in a mode of shielding the external light, and the reflecting part reflects the external light received in the designated direction so as to transmit the external light once again through the liquid crystal display part in a direction approximately normal to the display plane.

摘要： An optical system of an optical neural network model for parallel data processing is disclosed. Taking advantage of the fact that an auto-correlation matrix is symmetric with respect to a main diagonal and the weights for modulating the values of diagonals of the auto-correlation matrix are equal to each other, the configuration of an optical modulation unit is simplified by a one-dimensional modulation array on the one hand, and both positive and negative weights are capable of being computed at the same time on the other hand. In particular, the optical system makes up a second-order neural network exhibiting invariant characteristics against the translation and scale.
