Abstract: In this article, a 3-D vibration acceleration sensor based on fiber Bragg grating (FBG) is proposed. The sensor, with only four FBGs, adopts a spatially layered sensing structure and ...
Abstract: Based on Mach-Zehnder interference (MZI) principle, we propose a balloon-like optical fiber micro-liquid-level sensor and verify its performance through experiments. The sensor can ...
