改善强度型光纤传感器特性的措施

Methods Used to Improve the Intensive Optic Fiber Sensor

从理论上对强度调制型光纤传感器工作特性进行了推导，提出并实施了2种改善其特性的措施：一方面依据其工作原理，改变反射镜面的结构；另一方面，在测试时，采用2步测量的思想，以清除干扰的影响，改善传感器的工作特性。介绍了传感器具体结构及二次仪表。

Two methods to improve the Performance of intendve optic fiber sensor is Ptesented. on one hand we change the structure of the reflecting mirror according to its working theory. On the other hand, two steps are adapted in one test to eliminate the influence of disturhances. The structure of the sensor and the instrument are introduced.
