A multi-color sensor captures each of the simultaneously emitted spatial intensity color image patterns reflected from the surface of the specimen in a single wavelength-multiplexed sensor image, and a data processing apparatus in communication with the multi-color sensor determines properties of the surface based on an evaluation of the single wavelength-multiplexed sensor image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-color surface inspection system, method for inspecting a surface, and method for calibrating the multi-color surface inspection system","description":"A multi-color system for optically inspecting a surface of a specimen includes a multi-wavelength led array to illuminate the specimen with a multi-color light pattern including simultaneously emitted","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11994476","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.
