Home / Single-mode fiber optic pressure sensor
In this paper, we propose and experimentally validate an optical fiber structural sensor based on Mach-Zehnder interferometer (MZI) for pressure measurement. The sensor adopts a cascaded spliced single-mode-multimode-tapered single-mode fiber (SMF-MMF-Tapered SMF, SMTS) structure, taking advantage of the mode mismatch effect between different fiber. High-precision pressure sensing measurements are indispensable in critical fields such as national defense and security , oil and gas exploration , civil engineering and construction , and clinical medicine . As a new type of sensing technology, fiber optic pressure sensors have emerged among many pressure sensors with their unique advantages such as intrinsic pass. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
