Abstract: PROBLEM TO BE SOLVED: To constitute a compact optical disk array by using plural light beams branched by an optical branching means and recording or reproducing a signal on the signal recording surfaces of the corresponding disks. SOLUTION: The light beams from one of the semiconductor elements of an optical section 21 are reflected by a bending mirror 22 and are made incident on a combination prism 23. Then, the beams are reflected to an optical disk D1 by the dichroic filter of the prism 23 and are converged on the disk D1 through an objective lens 24. The returned light beams from the disk D1 are converged on one of the photodetectors of the section 21. In order to reproduce the signals on an optical disk D2, the light beams from the other semiconductor laser elements of the section 21 are converged on the disk D2 through the prism 23. The returned light beams from the disk D2 are converged on the other photodetector of the section 21.

Abstract: PROBLEM TO BE SOLVED: To make an optical pickup small size and light weight and also high reliable by casting a light beam made to enter a prism from a branching point of an optical path to the light receiving element from a surface formed with a semitransmission film. SOLUTION: The light emitting and receiving elements 21 and the optical pickup 20 using them are formed integrally with the prism 28 by its double refeaction material. As a result, return light from a magnetooptical disk MO is incident on the prism 28 and is splitted, and also these light beams reflected by the semitransmission film 31 formed on the bottom are reflected by the upper surface of the prism 28 based on a difference of refractive index between the double refractive material constituting the prism 28 and the open air. Then, the beams are guided to the bottom surface of the prism 28 and are incident upon 2nd and 3rd photodetectors. Therefore, it is not necessary to provide a total reflection film on the upper surface of the prism 28, and hence miniaturization and reduction in weight are feasible.

Abstract: PROBLEM TO BE SOLVED: To miniaturize a device and improve detecting accuracy by providing a semiconductor substrate having a photo-detector group and a polarization separating element in an optical pickup. SOLUTION: Light receiving elements PD1-PD3, a light emitting element LD for emitting light rays on a magneto-optical-signal recording medium and a polarization separating element 43 are mounted on a semiconductor substrate 42, and an optical pickup is constituted. The polarization separating element 43 comprises a double-refraction type single body, receives the returning light of the light rays reflected from the magneto-optical recording medium, separates the returning light and guides the light to the specified positions of the light receiving elements PD1, PD2 and PD3. Thus, the returning light reflected from the magneto-optical signal recording medium is securely separated into the direction determined by the optical axis of the double-refraction type material single body. Therefore, the improvement of accuracy and the compact production of the device are made possible.

Abstract: PURPOSE:To enable measurement of a size, a direction and a distribution state of a double refraction in a short time by making a luminous flux from a light source transmitted through a test specimen interfere with a light flux from the light source passed through a reference optical system. CONSTITUTION:A luminous flux from a light source 1 is incident on first and second optical paths 5 and 6 to obtain an outgoing luminous flux from a test specimen 12 through the first optical path 6. At the same time, the luminous flux is made to interfere with a reference luminous flux passed through the second optical path 5. Then, a plurality of interference states are formed with respect to different optical path length of the second optical path 5 and different direction of polarization of the luminous flux from the light source 1. Then, a computing processing is performed between detection data of interference images to determine a size of a double refractive index, a direction and a transmission wave face aberration of the test specimen 12.

Abstract: PURPOSE:To stably control a change in the beam path length of reference beam with high accuracy regardless of a change in the wavelength of a beam path, by controlling the angle of rotation of a parallel plate to change the beam path length of the reference beam allowed to interfere with the emitted beam from an object to be measured. CONSTITUTION:A part of the beams L1-L3 from a common beam source is transmitted through a beam splitter 2 and allowed to irradiate an object 1 to be measured to emit beam from the object to be measured while the remainder is reflected from the beam splitter 2 to obtain reference beam and emitted beam is allowed to interfere with the reference beam by the change of the beam path length of the reference beam. At this time, a transparent parallel plate 6 is arranged in the beam paths of the reflected beams L1, L2. The plate 6 consists of parts 6a, 6b whose thickness are respectively (d), (4d) and permits the respective beams L1, L2 to pass at equal refractivity and the respective beam paths of both beams are changed corresponding to a plurality of predetermined angles of rotation different from each other. Then, the angle of rotation of the parallel plate 6 is controlled on the basis of the change of the interference beam of the beams L2, L3 by a control means 20 and the beam length of the beam L1 is changed to allow the beam L1 to interfere with the emitted beam from the object 1 to be measured. By this method, the fine change of a beam path length is realized by the relatively large angular change of the plate 6.

Abstract: PROBLEM TO BE SOLVED: To provide a diffusion film having fine diffusion angles of high accuracy, a stereoscopic display device, including the diffusion film, and to provide a method for manufacturing the diffusion film.
SOLUTION: In the diffusion film, a first refractive index n1, a second refractive index n2, a curvature radius r and a distance a are determined so that the diffusion angle in a horizontal direction (direction Y) of light made incident in a direction X in a position separated by distance a in a horizontal direction (a direction Y) from a vertex P of an arc-shaped surface of a stereoscopic structure part 122, having a pitch pn (=2a=24) and transmitted by a second principal surface 120b of a base material 120 is a prescribed angle (±0.8°) or smaller (full width at half maximum of nearly 1°), and the pitch pn for each of the plurality of stereoscopic structure parts 122 is 2a (=24) or less. Consequently, the diffusion angle in the horizontal direction of the diffusion light by the fine diffusion film 12 can be suppressed, without fail, to a prescribed angle (±0.8°) or smaller (to an extent of full width at half maximum of 1°).

Abstract: PROBLEM TO BE SOLVED: To provide a lighting device which is thinned and relaxes steep luminance changes in boundary portions between divided regions having different light emission luminances, and also to provide a display device using the same.
SOLUTION: Each of light emitting elements 10 in each of light source modules 11 has an optical element 28 arranged respectively according to a chip 25. By refracting light from the corresponding chip 25 by each optical element 28, a luminance of light radiated right above the light emitting element 10 adjacent to the light emitting element 10 is set larger than a luminance of light radiated right above from the chip 25. When nine light emitting elements 10 in the light source module 11 emit light, each light emitting element 10 is prevented from lighting brightest right above each light emitting element 10, the luminance is gradually reduced in a line direction, a row direction or the like as it separates from a center region 11-A of the light source module 11, and, thereby, the steep luminance changes in the boundary portions between the light source modules 11 having different light emission luminances is relaxed.
