The element for displacing includes an arc-shaped arm at one end fixedly connected to the light source and slideably connected to a first support to adjust the zenith angle, and an element for pivoting the first support about the normal direction to permit adjustment of the azimuth angle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device for determining a bidirectional reflectance distribution function of a subject","description":"A device for determining a bidirectional reflectance distribution function of a subject, including a light source for producing an incident light that is directed onto a subject at a predetermined zen","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9625309","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.
