Study on Signal Processing of Optical Fiber Temperature Sensor

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.
