In this article, a distributed strain sensing system based on standard single-mode fiber is implemented using the Phase-Optical Frequency Domain Reflectometry (ϕ-OFDR). Compared to traditional amplitude cross-correlation algorithms, phase demodulation can achieve higher resolution, but it more susceptible noise interference. To address issue, an adaptive suppression algorithm adjacent window boundary continuity conditions has been proposed correct error jumps in unwrapping process and...
Liquid-level sensors are required in modern industrial and medical fields. Optical liquid-level can solve the safety problems of traditional electrical sensors, which have attracted extensive attention both academia industry. We propose a distributed sensor based on optical frequency domain reflectometry with no-core fiber. The sensing mechanism uses to capture strong reflection evanescent field fiber at liquid-air interface. experimental results show that proposed method achieve high...
