In this way a signal is obtained with greater amplitude than in the case of detection being performed with a single band. Thus the signal-to-noise ratio is improved in the sensor signal, dynamic range and the range is increased and the uncertainty of the measurement is decreased. It also eliminates the common noise present in the two bands of the probe signal and, in the case of using a balanced detector in detection, it improves the saturation characteristics of the detector, being able to achieve much larger signal amplitudes than in the conventional case."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distributed fiber optic sensing system and method based on stimulated brillouin scattering","description":"System and method of distributed sensing based on Brillouin stimulated scattering on optical fiber (3), consisting of separating the two signals of which the probe signal is composed and obtaining the","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9806805","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.
