Therefore, the phase difference between transmitting and receiving signals can be determined accurately and the distance to the objects can be accurately recognized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distance measuring method and equipment using optical signal","description":"The present invention relates to distance measuring method and equipment which consists of a stage that receives multiple signals reflected from the target of measuring through the operation of the sh","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9709669","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.
