We report a high-speed phase-sensitive optical coherence reflectometer (OCR) with a stretched supercontinuum source. Firstly, supercontinuum source has been generated by injecting an amplified fiber laser pulses into a highly nonlinear optical fiber. The repetition rate and pulse duration of the generated supercontinuum source are 10 MHz and 30 ps respectively. The supercontinuum pulses are stretched into 70 ns pulses with a dispersion-compensating fiber (DCF). This pulse stretching technique enables us to measure the spectral information in the time domain. The relationship of time-wavelength has been measured by modified time-of-flight method. We have built a phase-sensitive OCR with this stretched pulse source and a two-dimensional (2D) scanning system. The displacement sensitivity of our proposed system has been investigated. We have demonstrated high-speed 2D imaging capability and single-point dynamics measurement performance of our proposed system.
