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： Light-splitting elements are arranged in at least two columns and two rows to form two pairs 1a, 1b and 1c, 1d. Each element splits incident light into light rays and makes them fall on a portion of a photosensing section right under itself and an adjacent photosensitive cell. The element 1a splits the incident light so that a primary color ray C1 and its complementary color ray C1′ enter an adjacent cell 2b and an underlying cell 2a, respectively. The element 1b makes a primary color ray C2 and its complementary color ray C2′ enter an underlying cell 2a and an adjacent cell 2a, respectively. The element 1c does the same as the element 1b. And the element 1d makes a primary color ray C3 and its complementary color ray C3′ enter an adjacent cell 2c and an underlying cell 2d, respectively. These photosensitive cells 2 perform photoelectric conversion, thereby outputting an electrical signal representing the intensity of the incident light. By carrying out simple calculations between the outputs of these cells, a color signal and a luminance signal are generated.

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： In an embodiment, an optical pickup includes at least one light source for selectively emitting three light beams having blue, red, and infrared wavelengths, respectively, and an objective lens arranged so that each of the three light beams enters thereto. 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.
