Abstract: Provided is a position detection sensor including: a light-receiving unit that includes a first pixel, a second pixel and a calculation unit that performs center-of-gravity operation by using an intensity of first and second electric signals to calculate a first position. In the first pixel, as the incident position is closer to one end of the light-receiving unit in a second direction, the intensity of the first electric signal decreases. In the second pixel, as the incident position is closer to the one end, the intensity of the second electric signal increases. The calculation unit further calculates a second position on the basis of a first integrated value obtained by integrating the intensity of the first electric signal, and a second integrated value obtained by integrating the intensity of the second electric signal.

Abstract: A quantum simulator includes a pseudo speckle pattern generator, a main vacuum chamber, an atomic gas supply unit, a light beam generator, a photodetector, and an atom number detector. The pseudo speckle pattern generator generates a pseudo speckle pattern in the inside of the main vacuum chamber by light allowed to enter the inside of the main vacuum chamber through the second window. The pseudo speckle pattern generator includes a controller, a light source, a beam expander, a spatial light modulator, and a lens. The controller sets a modulation distribution of the spatial light modultor based on a two-dimensional pseudo random number pattern.

Abstract: A quantum simulator includes a chamber, a light beam generation apparatus, and a photodetector. The light beam generation apparatus includes a light source, an optical mask, a spatial light modulator, and a lens. The optical mask includes an inner region having a rectangular shape with a side parallel to a first direction or a second direction, and an outer region surrounding the inner region. 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: Provided is a shape measurement sensor including a light-receiving unit and a calculation unit. The light-receiving unit includes a plurality of pixel pairs. Each of the pixel pairs includes a first pixel and a second pixel that is disposed side by side with the first pixel along a first direction. In the first pixel, as an incident position is closer to one end of the light-receiving unit in a second direction, an intensity of a first electric signals decreases. In the second pixel, as the incident position is closer to the one end, an intensity of a second electric signal increases. The calculation unit calculates the incident position in the second direction for each of the pixel pairs on the basis of the intensity of the first electric signal and the intensity of the acquired second electric signal.
