The objective lens includes a first grating, and a second grating formed in the same plane as the first grating. The first and second gratings each have phase steps arranged concentrically around a center axis of a lens in a region in which all the three light beams pass, and are different in phase step positions. The first grating diffracts the three light beams having the blue, red, and infrared wavelengths in a 2nd order, a 1st order, and the 1st order, respectively. On the other hand, the second grating diffracts the three light beams having the blue, red, and infrared wavelengths in the 1st order, the 1st order, and the 1st order, respectively. As a result, the three light beams having the blue, red, and infrared wavelengths, which have been transmitted through the first grating and the second grating, are diffracted in a 3rd order, the 2nd order, and the 2nd order, respectively.

摘要： An imaging photodetection device (4) includes: a plurality of photodetectors (6) that are arrayed on a substrate (5) at least along a first direction; a transparent low refractive index layer (12) that is formed above the plurality of photodetectors; and a plurality of transparent high refractive index sections (13) that are embedded in the transparent low refractive index layer along the first direction. On a cross-section of the transparent high refractive index sections orthogonal to the substrate and along the first direction, central axes (14) of the transparent high refractive index sections are bent stepwise. Light that enters the transparent low refractive index layer and the transparent high refractive index section passes therethrough to be separated into 0th-order diffracted light, 1st-order diffracted light, and −1st-order diffracted light. Thereby, improvement in the efficiency of light utilization and pixel densification can be realized.

摘要： The solid state image sensor of this invention includes multiple units, each of which includes first and second photosensitive cells 2a, 2b and a dispersive element 1a facing the first cell 2a. The element 1a passes a part of incoming light with a first color component to the second cell 2b. The first cell 2a receives a smaller quantity of light with the first color component than that of the light with the first color component incident on the dispersive element. The second cell 2b receives a greater quantity of light with the first color component than that of the light with the first color component incident on the dispersive element. The quantity of that part of the incoming light with the first color component is calculated based on the difference between photoelectrically converted signals supplied from the first and second cells 2a and 2b and information representing the ratio of the quantity of the light with the first color component received by the second cell to that of the part of the incoming light with the first color component.

摘要： In a three-dimensional video display apparatus, accommodation and convergence among physiological characteristics of eyes are abandoned, thereby resulting in generation of unnatural three-dimensional video. For example, even when eyes are moved, a screen is not changed, and a cardboard effect and/or a miniature garden effect may be caused, so that the eyes may be greatly fatigued. Light emission sources 1R, 1G, and 1I, holograms 3R, 3G, and 3I, and a transparent display component 4 are provided, and a plurality of reflectors 6 are formed in the display component 4 so as to be positioned at intersections in a space lattice. Lights 2R, 2G, and 2I emitted from the light emission sources 1R, 1G, and 1I are incident on the holograms 3R, 3G, and 3I, respectively, and a plurality of diffracted converging lights 5G, 5B, and 5I are generated through the holograms 3R, 3G, and 3I, respectively, and each focused on light focusing points near the plurality of reflectors 6, and the diffracted converging lights 5G, 5B, and 5I are each reflected by the plurality of reflectors 6, and emitted to the outside through an emission surface 7s of the display component 4.

摘要： There is provided an information processing device which is capable of suppressing generation of stray light at the time of recording and reproduction of information, thus enabling quality information recording and reproduction. The information processing device includes: a radiation light source 2; and a converging section for converging rays emitted from the light source toward an information recording medium having a photosensitive layer 11b, wherein the converging section splits the rays into first and second rays 3′ and 3 respectively traveling through first and second spaces as divided by a plane at least containing a point optical axis L, and converges the first and second rays 3′ and 3 onto first and second points 12′ and 12 in the information recording medium 11, the photosensitive layer 11b being interposed between the first and second points 12′ and 12. Between the first and second points 12′ and 12, the first and second rays 3′ and 3 interfere with each other to form interference fringes, the interference fringes representing information to be recorded in the photosensitive layer 11b of the information recording medium 11.
