During the movements of the first and second sliding members, each transmitter emits laser beam toward the receiver of the same set by passing through a space above a photoresist-coated optical glass by 100 μm, no signal is generated at the receiver if the laser beam is not blocked, and a signal is generated at the receiver if the laser beam is blocked by at least one of a plurality of particles on the photoresist-coated optical glass."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for detecting heights of defects on optical glass","description":"A detection apparatus includes four sets of transmitter and receiver wherein the transmitters are on a first sliding member of a frame and the receivers are on a second sliding member of the frame; an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9733067","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.
