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 introduced optical fiber pressure sensor uses an AC driving source to drive the light emitting diode. The periphery of the pressure diaphragm is rigidly fixed, and the light intensity of the power supply is automatically compensated. Thus improving the accuracy, making the measurement stable performance.
