摘要： A focus detecting mechanism wherein the light reflected on an object surface (25) is diffracted by a hologram element (23). The diffracted light includes two astigmatic convergent beams which form least circles of confusion on long photodetector means (29) and (30) in the same plane close to a focal plane (22f) of a lens (22), and a focus signal is obtained on the basis of a differential output from these photodetecting means. Since two diffracted beams having least circles of confusion on the same plane, the photodetecting means can be placed horizontally, and a focus detecting mechanism can be made easily with an improved dimensional accuracy. In spite of the use of a hologram element, the fluctuation of wavelength can be absorbed, and the reliability of the device is very high.

摘要： A plurality of slant faces (1419) are formed on a substrate (1406). A polarized optical thin film is formed on the slant faces. The recess defined by the slant faces (1419) is filled with transparent material to form a small composite polarizing element. By this polarizing element, it is possible to detect magneto-optic signals excellent in transmissivity and extinction ratio and high in S/N ratio. Also, this polarizing element serves as the cover of the package (1408) of an optical head which houses a photodetecting element (1409) and a light emitting element (1411) integrally. Also, by use of an optical element having an optical path length adjustment function of varying the optical path length of the outgoing light beam from that of the incoming light beam, it is possible to eliminate the initial offset of the focal point error signals and to omit the adjustment at the same time. In this way, a small, simple and high-performance optical head used for magneto-optic recording and reproducing apparatus can be realized.

摘要： An integral optical head (1) comprises an actuator (50) whose moving part (5) is fitted with a laser optical system (20) including a semiconductor laser (22) and a light reception device. The moving part (5) is constituted by combining a metallic heat radiator (10) with a heat insulating member (9) made of plastics. The heat radiator is connected thermally to the semiconductor laser, and a coil of the actuator is fixed to this heat radiator through the heat insulating member. Accordingly, heat generated by the semiconductor laser is transferred to the heat radiator and is efficiently dissipated into the external space from the surface of the heat radiator. Because the coil and the laser optical system are thermally isolated, the laser optical system is not heated by the coil during the operation of the actuator. Further, because rigidity of a holder can be improved while avoiding the increase of the weight which will otherwise impede the operation, detrimental resonance at the time of driving of the actuator can be prevented. Accordingly, heat radiation/cooling characteristics of the semiconductor laser can be remarkably improved, and a stable operation and reliability of the apparatus can also be improved.

摘要： An optical pickup is capable of projecting laser beams having different polarization directions or different divergence angles from laser sources formed in a surface emitting laser array and varying the effective numerical aperture of an optical system provided with an objective lens and the like. The optical pickup has a high-degree compatibility with both a CD-standards optical disk having a low recording density and a large thickness and a DVD-standards optical disk having a high recording density and a small thickness. Furthermore, a plurality of laser sources can be formed in a compact space by adopting the surface emitting laser array, and the numerical aperture of the optical system can be controlled by making a selection of laser beams. Accordingly, it is possible to realize an optical pickup having compatibility by means of an extremely simple construction, and it is also possible to inexpensively provide a small-size high-performance optical pickup.

摘要： An image display apparatus in which the influence of difference in circuit characteristics can be dispersed among frames even if pixel data are phase-developed. The image display apparatus has a phase development circuit (380) which receives a first image signal (A1) having pixel data for driving pixels with a positive polarity voltage and a second image signal (A2) having pixel data for driving pixels with a negative polarity voltage, generates six phase development signals (V1-V6) which are obtained from the first and second image signals (A1 and A2) by developing the data lengths of the pixel data in units of a certain number of pixels into the expanded pixel data and outputs the six signals parallely to phase development signal output lines and a connection switching circuit (390) which switches the connection between the six phase development signal output lines (388a-388f) and the six signal supply lines (132a-132f). The order of developing the signals into the six phase development signal V1-V6 by a phase developing means and the combinations of the connection in the connection switching means corresponding to the development order are controlled and changed by a timing generating circuit block (200). The timing generating circuit block (200), in synchronism with vertical synchronization, changes the development order initially set in the previous frame to a different development order.

摘要： Ridges (312) are formed on the surface of a light guide body (311) at regular intervals. Except the sides (312b-1, 312b-2) of the ridges (312), a total reflection layer (313) is formed. A light-emitting means (322) is disposed on one end surface of a light guide means (307), and most of the emitted light enters the interior of the light guide body (311) through a surface of incidence (315). The light from the light emitting means (322) is propagated through the light guide body (311) and goes out from the side surfaces (312b-2). The internal light (305) passes through an optical axis conversion means (321) and then enters an object (302) to be illuminated substantially perpendicularly. The external light (306) passes through the object (302) and then enters an illuminator (303). The light further passes through the optical axis conversion means (321) in the illuminator (303), and is then reflected from the total reflection layer (313). The reflected light passes the optical axis conversion means (321) again perpendicularly and then enters the object (302) perpendicularly. The light further passes through the object (302) to enable the object to be recognized. The light is reflected by the total reflection layer (313) without any loss. In addition, even when the external light (306) enters the illuminator at an angle other than a right angle, it is reflected by the total reflection layer (313) without any loss and enters the object (302).

摘要： A front-placed surface illuminating device which has a high visibility both while illuminating and while not illuminating, and whose power consumption is small. The illuminating device which is placed in front of an object has a light guide plate which is a transparent flat plate and has dot-like light taking-out structures on the surface or at positions facing the surface and a light source facing to an edge of the light guide plate. The light source is, for instance, a point light source. The light taking-out structures are, for instance, column-shaped protrusions and are arranged two-dimensionally. When the illuminating device is placed in front of an object, light is projected to the object and, at the same time, light reflected by the object can be transmitted through the device with almost no diffusion. When the illuminating device is not operated, external light reflected by the object can be transmitted by the illuminating device with almost no diffusion. The point light source may be an LED or a light bulb. The low power consumption can be achieved easily.
