    Versatile Vibration Sensing Using a Tapered Photonic Crystal Fiber With a Featured Core

    Versatile Vibration Sensing Using a Tapered Photonic Crystal Fiber With a Featured Core by Haihu Yu, Huiru Zou, Zhuozhao Luo, Wenjing Gao, Xin Jiang

    Published 2020-01-01

    On the basis of intensity modulation, a vibration sensor using a tapered photonic crystal fiber (PCF) is demonstrated. The fiber is a solid-core PCF with a central air hole embedded in the core region. The addition of the air-hole initiates the core/cladding intermodal coupling, and conse...

    Characterization of Acoustic Source Signal Response in Oxidized Autocombusted Coal Temperature Inversion Experiments

    Characterization of Acoustic Source Signal Response in Oxidized Autocombusted Coal Temperature Inversion Experiments by Jun Guo, Wenjing Gao, Yin Liu, Guobin Cai, Kaixuan Wang

    Published 2025-07-01

    The measurement error of sound travel time, one of the most critical parameters in acoustic temperature measurement, is significantly affected by the type of sound source signal. In order to select more appropriate sound source signals, a sound source signal preference study of loose coal acoustic t...
