Abstract: A quantum simulator includes a chamber, a light beam generation apparatus, and a photodetector. The light beam generation apparatus includes a light source, a spatial light modulator, and a lens. Each of pixels of the spatial light modulator has a rectangular shape with a side parallel to a first direction or a second direction, and the pixels are arranged at regular intervals along the first direction and the second direction. When an xy coordinate system including an x axis parallel to the first direction and a y axis parallel to the second direction is set on an image plane, the light beam generation apparatus forms and regularly arranges focusing spots such that a minimum value of a difference between x coordinate values and a minimum value of a difference between y coordinate values of center positions of the focusing spots are longer than a non-overlapping distance.

Abstract: A plurality of pixels are arranged two-dimensionally in a matrix and individually include a first photosensitive portion and a second photosensitive portion. A plurality of first wirings connect a plurality of first photosensitive portions to each other for every row. A plurality of second wirings connect a plurality of second photosensitive portions to each other for every column. A first reading unit 21 is arranged to read signal data through at least some of the plurality of first wirings. A second reading unit 31 is arranged to read signal data through at least some of the plurality of second wirings. The first reading unit 21 has a reading pixel setting unit 26 arranged to set, based on signal data read in the first frame, a pixel group for reading signal data in a second frame subsequent to a first frame from the plurality of pixels.

Abstract: An object is to simply and easily evaluate differences in behavior of the eyes of subjects. A binocular measurement system 1 includes a photodetector 7 that detects reflected light from the right eye ER and the left eye EL of a subject, and outputs image signal of the reflected light, a feature amount calculating unit 11 that calculates a feature amount corresponding to the right eye ER and a feature amount corresponding to the left eye EL based on the image signal, and a comparison value calculating unit 13 that calculates, based on the two feature amounts, a comparison value obtained by comparing the two feature amounts.

Abstract: A light detection device detects an incident position of light. The plurality of pixels are arranged two-dimensionally in a matrix and individually have a first photosensitive portion and a second photosensitive portion. The first circuit connects a plurality of first photosensitive portions to each other for every row. The second circuit connects a plurality of second photosensitive portions to each other for every column. The first reading unit reads signal data through the first circuit. The second reading unit reads signal data through the second circuit. The first circuit includes row switches arranged to switch electrical connection and disconnection between first photosensitive portions adjacent to each other in the same row.
