分布式光纤测温系统及高速数据采集与处理

High Speed Sampling and Data Processing in Optical Fiber Distributed Temperature Measurement System

分布式光纤测温系统是一种用于实时测量空间温度场分布的光纤传感系统 ,在系统中 ,光纤本身既是传输媒体也是传感媒体。讨论了系统的工作原理、设计思想、系统构成、高速数据采集以及瞬态采样平均技术 ,该系统已应用于石油测井。

The optical fiber distributed temperature measurement system is developed for the real time measurement of temperature field in space.In the system,the optical fiber is the transmissive medium as well as the sensitive medium.In this paper,we discuss the theory,design,and composition of the system,and then study the high speed sampling and sample average technique applied in the system.Now this system has been applied in well loging.
