The method comprises analyzing the measurement signals of a first subset of longitudinal sensing portions to provide a first zone (306a) having a first sensing function and analyzing the measurement signals of at least a second subset of longitudinal sensing portions to provide at least a second zone (306b) having a second, different, sensing function. The different sensing functions may include detecting different events of interest. In some embodiments the geometry of the fiber may provide different sensing zones (406a, 406b)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fibre optic distributed sensing","description":"A method of distributed fiber optic sensing is described in which an optical fiber (104) is interrogated with electromagnetic radiation; back-scattered radiation is detected; and the returns are proce","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9739645","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.
