Paper Abstract

This paper proposed using continuous wavelet transform to analyze the non-stationary vibration in the distributed vibration sensor based on phase optical time domain reflectometry (OTDR). The continuous wavelet transform approach allows detection of both the frequency and time information of vibration simultaneously. Distributed vibration measurements of 200Hz and 200 Hz to1 kHz sweep events over 20cm length have been demonstrated using the single mode fiber.
