光纤传感器是近年来迅速发展起来的一种新型传感器,它与机械、气动和和电子传感器比较,具有灵敏度高、动态响应快且不受电场和磁场干扰的优点。目前,它已应用于测量各种机械量(如位移、压力、加速度等)。它与微型计算机相结合,进行位移测量,不但精度高,而且移动性好。本文所介绍的反射式光纤位移传感器实验台是为满足 Optical fiber sensor is a new sensor developed rapidly in recent years. Compared with mechanical, pneumatic and electronic sensors, optical fiber sensor has the advantages of high sensitivity, fast dynamic response and no interference from electric and magnetic fields. Currently, it has been used to measure various mechanical quantities (such as displacement, pressure, acceleration, etc.). It combines with the microcomputer for displacement measurement, not only with high precision and good mobility. This article describes the reflective optical fiber displacement sensor test bench is to meet
