The processor is configured to control the light modulator to form a computer generated hologram (CGH) wavefront from the light modulator corresponding to an image to be produced in the far field. The processor is also configured to control the light modulator to selectively direct the CGH wavefront. The light modulator may comprise an angular light modulator (ALM) comprising the plurality of pixels, each of the plurality of pixels having an OFF state and an ON state, the ALM arranged to direct the amounts of light in the direction as the pixels transition between the ON state and the OFF state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for angular and spatial modulation of light","description":"A light projection system comprising a light modulator that comprises a plurality of pixels each capable of selectively directing a corresponding modulatable amount of light, and a processor coupled t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11509871","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
