The collecting unit collects multi-way signal light obtained after the emitted monochromatic light is reflected by the sample surface. The processing unit includes a photoelectric conversion module, an adding module and a testing module. The photoelectric conversion module converts the collected multi-way signal light respectively to multi-way electrical signals. The adding module performs an adding operation for the multi-way electrical signal to obtain an operation result. The testing module tests a quality parameter of the sample according to the operation result, and outputs a testing result."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical testing system and method","description":"An optical testing system includes: a testing probe, a collecting unit, and a processing unit, wherein the testing probe includes a plurality of spectrum photodiodes used for emitting and casting mono","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9797874","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.
