摘要：
The development of an automated distributed fiber optic sensor based on the Brillouin loss principle is presented. A description of the system configuration and signal processing techniques used in the measurement and control system are included. The system can achieve 0.5-m spatial resolution with +/- 1 degrees C temperature or +/- 20 mu m/m strain measurement precision. (C) 2000 Society of Photo-Optical Instrumentation Engineers.
