Dual-Value Signal Discrimination of Reflection Optical Fiber Displacement Sensor

Li Hung;He Kankan;Zhou Shuquan (Shanghai University, Shanghai 201800)  
This paper analyses physical mechanism of the dualvalue signal of the reflection intensity modulated optical fiber displacement sensor. We have introduced monitoring signal of sensor output peak voltage in the experiment, which we can discriminate output voltage corresponds to the smaller displacement value or to the bigger one. It makes it possible to apply this kind sensors of in practice.
