【 摘 要 】

To improve the performance of distributed fiber vibration sensing system used in smart power plant, time division control optical pulse width method is proposed. It used periodic optical pulses during transmitting and a series of signal processing after received the backscattered signal. By using this method, system positioning accuracy is better than the single pulse width case. It can also compensate for the defects of low sensitivity and weak signal strength at long distance.
