高精度光纤压力传感器的研究

Research on High-precision Fiberoptic Pressure Sensor

介绍的光纤压力传感器采用交流驱动源驱动发光二极管、压力膜片的周边采用刚性固定，对电源发光光强进行自动补偿。从而提高了精度，使测量时性能稳定。

The paper describes a kind of fibre optic pressure seuor using the deformation of diaphragm to module the light intensity. This sensor bresks the traditional way of using D.C. source to drive LED source, but uses A.C snuroe to drive LED source. This paper relates the measurement prinaples, smsor structure and measurement drcuit, and destribe the expedmental result curve.
