    Abstract: A method and an apparatus for driving an optical recording medium for recording and/or reproducing various information for the optical recording medium, in which the output power ratio of the light source may be reduced for recording and reproduction, for optical recording media of different sorts, or for respective recording surfaces of a multi-layered optical recording medium, so that optimum characteristics may be realized even with use of an easy-to-fabricate light source or a light source with a smaller light output rating. The intensity of a light beam emitted on an optical recording medium (102) by an optical head (104) is controlled by optical coupling efficiency varying elements (214, 215) depending on the sort of the optical recording medium (102), recording surfaces of a multi-layered optical recording medium, recording surfaces in a multi-layered optical recording medium or on the operating modes, in such a manner that the intensity of the light beam emitted on the optical recording medium (102) may be significantly varied without drastically increasing the output power ratio on the side light source (2).

    Abstract: A liquid crystal device capable of imparting a desired phase distribution to transmitted light without need to perform complex calculation. The manufacture and evaluation of the liquid crystal device can be easily conducted. A liquid crystal layer (120) sealed in the space between glass substrates (100, 110) has a given thickness distribution due to the unevenness of a sub-substrate (111) provided on the inner side of the glass substrate (110). Electrodes (130, 140) provided on both sides of the liquid crystal layer (120) are planar and parallel. Therefore, the spacing between the two electrodes (130, 140) are always constant, and the distribution of the electric field applied to the liquid crystal layer (120) is uniform. As a result, the shape of the phase distribution to which the light transmitted through the liquid crystal is subjected is determined only by the thickness distribution of the liquid crystal layer, and the magnitude is determined by the value of the voltage applied between the electrodes. Thus, since the distribution of the electric field applied to the liquid crystal layer is uniform, the phase distribution of the transmitted light is easily and accurately calculated by using the thickness distribution of the liquid crystal layer.

    Abstract: A low-profile biometrics authentication system capable of achieving high security level authentication is provided. A biometrics authentication system 1 includes a light source 10, a light guide section 11A, a diffraction section 11B, a microlens array 12, an image pickup device 13, an image processing section 14, a pattern storing section 15, an authentication section 16, a voltage supply section 17, a light source driving section 181, an image pickup device driving section 182 and a control section 19. When light L0 emitted from the light source 10 propagates through the light guide section 11A by total reflection, and then enters the diffraction section 11B, light L1 diffracted at a different angle from an incident angle is generated. Thereby, the light guide section 11A functions as a surface-emitting light source, and total reflection conditions in the light guide section 11A are not satisfied, and the light L1 is guided to the outside of the light guide section 11A, thereby light is sufficiently applied to the inside of the living body 2.

    Abstract: An optical disc comprising a substrate and a recording layer and a light-transmitting layer, laid on a substrate one upon the other in the order mentioned. A light beam is applied to the recording layer through the light-transmitting layer, to record and/or reproduce data on the disc. The light-transmitting layer is composed of at least two material layers laid one on the other and having different refractive indices. The disc is designed to set the spherical aberration caused by an objective lens that focuses the light beam used to record and/or reproduce data, at a value close to a minimum.
