    摘要： An obtainment unit (311) obtains characteristics information of a biometric image captured while casting first or second illumination light onto an authentication target. The first illumination light includes light of a first wavelength, and the second illumination light includes light of the first wavelength and light of a second wavelength. A reading unit (312) reads characteristics information of a biometric image captured while casting illumination light cast onto the authentication target from a storage unit that stores first characteristics information of a first biometric image and second characteristics information of a second biometric image. The first biometric image is captured while casting the first illumination light onto a registration target, and the second biometric image is captured while casting the second illumination light onto the registration target. A calculation unit (313) calculates a similarity between the obtained characteristics information and the characteristics information read from the storage unit, and an authentication unit (314) conducts authentication.

    摘要： An illumination apparatus is disclosed, which includes a light source configured to generate light for an illumination area to be illuminated, and a diffraction grating element provided between the illumination area and the light source, and including a plurality of diffraction gratings arranged in a two dimensional array. A distribution of grating intervals of the diffraction gratings in the diffraction grating element has a characteristic such that a center region, along a predetermined line in a plane of the two dimensional array, has a greater grating interval than an end region.

    摘要： An illuminating device (10) comprises a pair of light sources (12) and a rod-like photoconductor (14). The rod-like photoconductor (14) includes a pair of planes of incidence (16) entered by the light from the light sources (12), a reflection surface (20) having a plurality of prisms (18) and an exit plane (22) located opposite to the reflection surface (20). The width (A) between the reflection surface (20) and the exit plane (22) at the planes of incidence (16) of the rod-like photoconductor (14) is smaller than the width (B) of the light sources (12) in the same direction. Moreover, the width (C) between the reflection surface (20) and the exit plane (22) at the central portion of the rod-like photoconductor (14) is different from the width (A) between the reflection surface (20) and the exit plane (22) at the plane of incidence (16) of the rod-like photoconductor (14). As a result, the brightness distribution of the light exiting from the rod-like photoconductor (14) becomes uniform. The illuminating device (10) is combined with a plate-like photoconductor (32) to make up a planar illuminating device (30). Also, the planar illuminating device (30) is combined with a liquid crystal panel (42,52) to make up a liquid crystal display apparatus (40,50).

    摘要： A method for detecting a tracking error in a process of tracking a groove track on a recording medium includes the steps of: irradiating a first light spot (SP1) onto a groove track (15) on a recording medium (1) as a focused light beam for carrying out recording, reproducing, or erasing of information on the groove track of the recording medium; and irradiating a second (SP4) and a third (SP5) light spots onto an area around the groove track on the recording medium as focused light beams simultaneously with the irradiation of the first light spot, the second and third light spots are irradiated onto an area around the groove track on one side of the first light spot in a manner such that each of the second and third light spots covers both an inside and outside of the groove track.
