A first fiber grating reflects light at a first wavelength. A second fiber grating reflects light at a second wavelength. The system also has a reference optical fiber. An optical read-out arrangement generates light at the first and second wavelengths. The light is injected in the sensing optical fiber and in the reference optical fiber. A first phase difference is measured between light at the first wavelength emanating from the sensing optical fiber and the reference optical fiber. In addition, a second phase difference is measured between light at the second wavelength emanating from the sensing optical fiber the reference optical fiber. A measurement result is based on a difference between the first phase difference and the second phase difference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical fiber-based sensor system having dual optical fibers providing measurements of a first and a second phase difference","description":"An optical fiber-based sensor system includes a sensing optical fiber having fiber gratings that reflect light at respective wavelengths.
