Using one optical fiber as the sense and conduction medium of the temperature information,distribution pattern's optical fiber temperature sensor can measure the temperature charges along the optical fiber line.The signal processing of this sensor is to make effort to remove noise and interruption from the detector output signal,in which way the temperature display and date can be obtained accurately and rapidly,and this has a great value and application potential in solving such problems as the real-time control,precise measure of the large-scale structure and the combination of the intelligent materials structure.This paper makes a thorough profound distribution pattern's optical fiber temperature sensor based on the ratio of Anti-Stokes and Stokes.And consequently the signal processing system of the sensor is established.
