Abstract: An optical pick-up device for use in an optical disc information recording/reproducing apparatus is provided. In the present optical pick-up device, the functions of two or more separate optical elements provided in the prior art structure are combined or integrated in a single element to reduce the total number of separate optical elements provided in the device. In particular, use is made of a diffraction grating rather than lenses and/or lenses are formed as holo lenses. A diffraction grating and a holo lens may be formed substantially in the shape of flat plates, so that many optical components can be put together to define an integrated subassembly, which reduces the total number of discrete elements, facilitates manufacturing and eliminates the necessity of adjustments among optical elements once set.

Abstract: An optical deflection element receives incident beam and deflects the incident beam with an arbitrary deflection angle. The optical deflection element includes a plurality of unit members which are successively stacked and each including an electrooptic layer, an electrode layer formed on a surface of each electrooptic layer, and an insulator layer formed on the surface of each electrooptic layer adjacent to the electrode layer, where a boundary between the electrode layer and the insulator layer is inclined to an optical axis of the incident beam.

Abstract: An optical imaging apparatus according to the present invention comprises a flat multilens array having a number of lenses arranged in a row and a flat multiprism array having a number of prisms also arranged in a row and located behind the multilens array such that its individual prisms are aligned with the individual lenses. Two prism surfaces (flat reflecting surfaces) are positioned at one side and a single lens surface (curved surface) at the other and multiple combinations of such surfaces are lined up in an array. Each lens or each prism has on its front end a light intercepting screen plate having a substantially oblong opening which is shorter in the direction of the array and longer in a direction perpendicular thereto, or the aperture of each prism and/or each lens itself is shaped so. For the correction of abberations, one or more additional lenses of different curvatures are stacked on the front end of each lens to constitute a composite lens system. The multiprism array is replacable by a multiroof prism array.

Abstract: A device for writing optical information including a roof mirror array, a lens array, an optical-path separator, a mirror member, a housing, and a self-scanned recording element. The roof mirror array, the lens array, the optical-path separator, and the mirror member are retained by the housing in a prescribed mutual positional relationship. The housing has a pair of slits, one of which is covered with the light-signal producing surface of the self-scanned recording element. The housing is shaped such that the light-signal producing surface of the self-scanned recording element is held in registration with an object surface on which an unmagnified object image would be formed by the lens array and the roof mirror array.

Abstract: A roof mirror array for use in an optical imaging apparatus includes a front and a rear surface on which a succession of chevron faces of an equal configuration are formed in a manner such that the peak of one of the surfaces is aligned with the valley of the other surface. The chevron faces on at least one of the front and the rear surface define a roof mirror surface. The array includes a holding frame which surrounds the outside portion of the central region between the chevron faces.

Abstract: An optical system scans an original document vertically and focusses an image of a linear portion of the document onto a photosensor array which comprises a large number of photosensor elements arranged in a line. The photosensor elements are sequentially enabled always in one direction to effect horizontal scan of the linear portion of the document. The optical system alternately scans up and down to maximize the vertical scanning speed. Reversal means control the optical system and photosensor array to effect rightward and leftward horizontal scan when the vertical scan direction is upward and downward respectively. The optical system may comprise two imaging systems to project erect and inverted images on the photosensor array respectively, the reversal means comprising a shutter for selectively unblocking the imaging systems. Alternatively, the output signals of the photosensor elements may be stored in a bi-directional shift register or a random access memory with a bi-directional address counter, and read out in a direction corresponding to the direction of vertical scan.

Abstract: A scan line of an original document is divided into first and second halves, and first and second optical systems focus first and second images of the first and second halves onto a linear array of photosensitive elements such as photodiodes. The first and second images are each coextensive with the array and superimpose. A rotary shutter alternatingly blocks the first and second images so that only one of the first and second images is incident on the array at any time.
