基于反射型TDM的高精度光纤传感器系统设计
Design of high precision optical fiber sensor system based on reflective TDM
摘要
Abstract
This paper studies the effect of unmodulated depth of laser on output intensity in order to obtain higher detection accuracy and larger test range, based on the spectral absorption technique, it designs a reflec-tive time-division multiplexing (TDM) optical fiber sensor system to complete the multi-point gas concentra-tion detection with single fiber. The paper designs a high-precision light source driving circuit which is suit-able for multi-point detection. Ensuring the absorption peak can be aligned, experiment results show that the optical fiber sensor system has higher accuracy and meets the requirements of long-distance measurement.关键词
