The measurement elements include a ring resonator (1143) in transmission mode including a first coupler (1141) and a second coupler (1142) respectively, which couple a first arm (111) and a second arm (112) respectively of the SAGNAC interferometer to the ring resonator, in such a way that the two light waves travel in opposing directions of travel (1143H, 1143AH)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fibre-optic interferometric measurement device comprising a ring resonator, gyrometer and inertial attitude or navigation unit comprising such a device","description":"A fiber-optic interferometric measurement device (100) intended to measure a physical parameter (QR), includes: a wide-spectrum light source (103); a SAGNAC fiber-optic interferometer (110), in which ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9702700","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.
