双同心圆光纤位移传感器测试系统改进及优化分析

光纤传感器是把光纤作为信息传输的重要媒质，是光纤、光通信技术持续发展的产物。在光传输过程中，由于受到各种主客观因素的影响，广播特征参量极易受到外界的干扰，需要准确把握光波特征参量变化情况，知道其物理量变化情况，这就需要充分发挥光纤位移传感器的作用。因此，本文作者以双同心圆光纤位移传感器为例，对其测试系统改进及优化予以了探讨。

The improvement and optimization analysis of the test system of the double concentric circular optical fiber displacement sensor

Optical fiber sensor is an important medium of information transmission,and it is the result of the continuous development of fiber optic and optical communication technology.In optical transmission process, due to the influence by various kinds of subjective and objective factors, the characteristic parameters of the radio easily by external interference and need to accurately grasp the characteristics of light waves parameter change and know the status of the change of the physical quantity, which need to give full play to the role of fiber optic displacement sensor.Therefore, the author takes the dual concentric circular fiber displacement sensor as an example,and discusses the improvement and optimization of the test system.
