The relay lens comprises a combining device, that is adapted to combine the first and the second light beams. The optical projection device further comprises a projection lens that is adapted to project the intermediate image onto a screen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"3D optical projection device","description":"An optical projection device comprises an imaging device adapted to generate a first and a second image in a first and a second light beam, respectively, a first converting device that is adapted to c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8534841","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.
