Direct Detection Φ-OTDR System Based on the Different Pulse Width Method
Conventional vibration demodulation typically utilizes nearby sample points in conjunction with pulses having relatively wide width for demodulation, which has drawbacks, including inconsistent spatial positions corresponding to adjacent sampling points and limited spatial resolution. This research proposes a novel quantitative vibration demodulation technique based on direct detection Φ-OTDR to address this issue. At a set repetition frequency, this technique alternately emits optical pulses with comparable but different pulse lengths. To precisely demodulate the vibration phase, it obtains two optical intensity signals at the same fiber position, which have different initial phases but virtually similar vibration-induced phase shifts. Compared with the conventional demodulation method, the proposed technique achieves a signal-to-noise ratio (SNR) improvement of 9.4 dB. By not relying on the data acquisition card's (DAQ) sampling rate, this technique reduces the acquisition system's cost and performance requirements while avoiding the spatial resolution deterioration associated with conventional demodulation using nearby sampling points.
