The method includes the providing of a heterodyne fiber-optic interferometer having a demodulator and an associated carrier frequency. The method also includes the determining of demodulator excessions. The detecting of the demodulator excessions and the determining of an appropriate correction factor is based on information from the instantaneous carrier frequency. The method also includes the introduction of the appropriate correction factor to the demodulator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic range extension of heterodyne fiber-optic interferometers via instantaneous carrier measurement","description":"A method of dynamic range extension for heterodyne fiber-optic Interferometers, and more particularly towards the use of instantaneous carrier to extend the dynamic range of heterodyne fiber-optic int","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667349","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.
