光纤传光型压力传感器的研究

Study on Pressure Sensor of Fiber Optical Transmission Type

本文介绍了微功耗压力传感器光纤耦合的原理及利用单光纤传输双路信号(测量与参考)进行比例测量的方法。讨论了这些措施对测量系统的稳定性、漂移、噪声抑制、抗干扰等性能指标的改善。

The principle of fiber-optics coupling for micropower dissipation pressure transducers and the proportional measurement method using single mode fiber-optics for dual-signal transmission have been presented in this paper. The improvement of the measuring system performance such as stability, drift, noise-suppression and interference-resistance by adopting these measures has been discussed.
