The processor is programmed to control a first set of the pixels to transition between the OFF state and the ON state while the beam is incident on the pixels. An amount of light is selectively directed in a direction by the first set. The processor is also programmed to control a second set of the plurality of pixels to remain in the OFF state while the beam is incident on the plurality of pixels. As a result, the ALM operates as a spatial light modulator and an angular light modulator of the beam of light."},"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, including a light source to provide an output beam of light, an angular light modulator (ALM) comprising a plurality of pixels, each pixel having an ON state and an OFF stat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11503255","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.
