提出并实施了两种改善强度调制型光纤传感器特性的措施:依据其工作原理,改变反射镜面的结构;再采用两步测量方法,以清除干扰,改善传感器的工作特性.这种传感器已应用于实际所研制的光纤位移测量仪及光纤振动测量仪.
Two measures to improve the characteristics of intensity-modulated optical fiber sensors are proposed and implemented: according to their working principle, the structure of the reflecting mirror surface is changed; then the two-step measurement method is adopted to eliminate the interference and improve the working characteristics of the sensor. The sensor has been applied to The actual development of optical fiber displacement measuring instrument and optical vibration measuring instrument.
