The image light is formed of a plurality of diffracted light beams and a plurality of zero-order light beams, which are generated by the illumination light and the liquid crystal light valve. In the exit pupil, an illuminance peak due to the zero-order light beam corresponding to the first light beam is disposed at a position different from a position of an illuminance peak due to the diffracted light beam corresponding to the second light beam."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projector","description":"A projector includes an illumination device adapted to emit a plurality of light beams, which includes a first light beam and a second light beam, as illumination light, a liquid crystal light valve, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9618767","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.
