The two surfaces of the diaphragm and a surface of optical element and either surface of the diaphragm are partially reflecting surfaces and respectively define two optical path distances (OPDs) that produce preferential reflections and interference patterns at different optical frequencies or wavelengths that are respectively affected by pressure or temperature. Arranging the OPDs such that the fundamental frequency and harmonics of preferential reflections one OPD do not coincide with the fundamental frequency or harmonics of another OPD provides for both temperature and pressure measurement with a single interrogator and without complex spectral analysis."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sapphire sensor apparatus including an optical fiber for measuring pressure and temperature","description":"A sensor apparatus and system for measuring pressure, temperature or both with a single interrogator includes a sensor having a cavity, a diaphragm and an optical element or base for conducting energy","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10495525","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.
