一种脉位调制光纤传光式压力传感器的研究

Study on Optical Fiber Pressure Transduscer by PPM

介绍了微功耗压力传感器光纤耦合的原理以及使用单光纤传输双路信号进行比值测量的方法．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 optical fiber couplign for the micropower dissipation pressure transducers and the propornal measurement method using of single mode fiber-optics for daul-signal transmission have been presented in this paper.The improvement of the system such as stability.drift,noise-suppression and interference-resistance by adopting these measures has been discussed.
