This technique allows the use of relatively simple, low-cost spherical mirrors while providing the desired dense spot patterns."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multipass cell using spherical mirrors while achieving dense spot patterns","description":"A technique for designing a multipass optical cell utilizes an iterative artificial intelligence-based optimization process based upon evaluation of direct ray tracing with mirrors simulated as having","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531659","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.
