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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pseudo speckle pattern generation device, pseudo speckle pattern generation method, observation device, and observation method","description":"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.
