Study on Signal Processing of Optical Fiber Temperature Sensor

信号处理系统是分布式光纤温度传感器的重要组成部分，它的研究和设计对降低探测器和放大器的输出噪声，提高传感器的时间分辨率和温度分辨率有重要的意义。本文从提高时间分辨率的角度介绍了传感器对信号处理系统的要求，提出并行取样积分器方案及其所能达到的时间分辨率；介绍了由此而建立的信号处理系统。

Signal processing aystem is an important part of distributed optical fiber temperature sensor,the study on signal processing system of this sensor has great significance on reducing the output noise of de-tector and amplifier.and improving the resolution of optical fiber tempetature sensor.In this paper.from the point of improving the time resolution,the authors introduce the requirments of the sensor on the Signal Pro- cessing system. and propose an implemental method of parallel sampling integration as well as its time resolu- tion. The cortesponding signal processing system is also introduced.
