摘要： An optical unit as used for an optical sensor, including a substrate, one or more optical elements fixedly supported by the substrate, and an protecting arrangement associated with the substrate and at least one of the optical elements, for protecting each associated optical element from thermal stresses exerted thereto due to a difference in thermal expansion coefficient between the substrate and the associated optical element. The protecting arrangement may consist of at least one intermediate body interposed between the substrate and the associated optical element. Each intermediate body has a thermal expansion coefficient close to that of the associated optical element. Alternatively, the protecting arrangement may consist of a constricted protecting portion such as protrusions or slots formed on one of the associated optical elements and the substrate, such that the protecting portion defines an adjoining interface between the optical element and the substrate, or is located adjacent to the adjoining interface.

摘要： An apparatus for displaying a three-dimensional image of a plurality of tomographic images by storing pictorial information of a tomographic image in an image convering element, forming interference fringes between a reading light beam which is transmitted through the image converting element and is modulated in accordance with the pictorial information stored therein and a reference light beam, and recording the interference fringes on a photographic plate. A three-dimensional image is reproduced by projecting the reference light beam onto the thus developed photographic plate. The image converting element is formed by a Pockels readout optical modulator. An intensity and position of a coherent light beam is modulated in accordance with the pictorial information of the tomographic image, and the thus modulated coherent reading light beam is made incident upon the Pockels readout optical modulator.

摘要： An optical unit having an electrooptical element whose optical properties are changed as a function of a voltage applied thereto to modulate an incident light in response to the applied voltage. The optical unit includes a shielding member for electrically shielding at least a portion thereof which includes the electrooptical element from an external electric field. The shielding member protects the electrooptical element from an influence of an external electric field on an electrooptical effect of the electrooptical element. The shielding member may be an electrically conductive member, such as a metallic casing accommodating the electrooptical element, or an electrically conductive layer covering a housing accommodating the element.

摘要： An optical device including an optical bench and a plurality of optical elements. The optical bench has first and second supporting sections, separated from each other, each having at least two supporting surfaces. The optical elements secured to the first and second supporting sections have cylindrical bodies, so that these optical elements contact the sections only by lines. Therefore, the relative positions of each optical elements in the optical device are maintained for a long time without being affected by temperature variation in the atmosphere surrounding the optical device.

摘要： An optical unit or an optical sensor through which a light beam is propagated in a predetermined direction, having an optical component which includes at least one first single crystal element each having a property of causing dextrorotation of a plane of polarization of the light beam during propagation of the beam, and at least one second single crystal element each having a property of causing levorotation of the plane of polarization of the light beam. The first and second single crystal elements are superposed on each other in a direction perpendicular to the direction of propagation of the beam. The single crystal elements may be bonded together by direct solid-solid reaction, or by diffusion of a material of a thin bonding film interposed between the adjacent single crystal elements. The single crystal elements also exhibit a magnetooptical or Faraday effect when used in a magnetic-field sensor, for example.
