A Smart Graded-index Multimode Fiber Based Sensor Unit for Multi-parameter Sensing Applications
Abstract: We demonstrate a smart optical fiber sensor unit to realize a multi-parameter sensing, including temperature, curvature and strain or displacement. The sensor unit is composed of a Bragg grating in graded-index multimode fiber and a Fizeau cavity.
