  • Publication number: 20230101292
    Abstract: A pseudo speckle pattern generation apparatus includes a light source, a beam expander, and a spatial light modulator. The spatial light modulator has an intensity modulation distribution based on a pseudo speckle pattern calculated from a pseudo random number pattern and a correlation function, receives light output from the light source and increased in beam diameter by the beam expander, spatially modulates the received light according to the modulation distribution, and outputs modulated light.

  • Patent number: 11567450
    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 modulator based on a two-dimensional pseudo random number pattern.

  • Patent number: 11300800
    Abstract: A pseudo speckle pattern generation apparatus includes a first spatial light modulator, a first lens, a second spatial light modulator, a second lens and the like. The first spatial light modulator has a first intensity modulation distribution based on a pseudo random number pattern, and spatially modulates intensity of light output from a light source and increased in beam diameter by a beam expander. The second spatial light modulator has a second intensity modulation distribution based on a filter function, is provided on a plane where a Fourier transformed pattern is generated by the first lens, and spatially modulates intensity of the light reached through the first lens. The second lens optically Fourier transforms a pattern of the light output from the second spatial light modulator to generate a Fourier transformed pattern as a pseudo speckle pattern.
