  • Optically addressable pixelated spatial light modulator and spatial light field modulation method
    Patent number: 12416899
    Abstract: An optically addressable pixelated spatial light modulator, comprising: a laser light source, a structured light field encoding projection module, and a superpixel metasurface device. The structured light field encoding projection module comprises a structured light field encoding module, which encodes a laser beam emitted by a laser light source into a structured light beam according to the modulation amount distribution of a target light field. The superpixel metasurface device comprises a plurality of unit cell structures, with each unit cell structure serving as a light field modulation pixel point. Each unit cell structure comprises a plurality of sub-wavelength micro-nano structures, and the unit cell structure generates a light field modulation amount under the action of the structured light beam for the light field modulation.
