摘要
在分析了瑞利解调方法的优势与不足的基础上,提出了一种实验修正方法。以空间分辨率作为参考,否定了几种常见的微弱信号提取方法。最后介绍了基于瑞利解调方法的单模分布式光纤测温系统在冻结井温度场监测中的应用。
On the base of analyzing the advantages and shortcomings of Rayleigh demodulation method, the paper advances a test-revised method. In reference to special resolution, it negates several normal weak signal abstract methods. Finally, it presents the application of single-mode distributed optical fiber measuring temperature system in the monitoring of frozen well temperature field
