Abstract
We propose and experimentally demonstrate a Brillouin optical correlation domain analysis system both with high-speed random accessibility and with temporal gating scheme to extend the measurement range. High-speed dynamic strain measurement at multiple points selected arbitrarily along an elongated measurement range is demonstrated. We successfully measured the dynamic strain at the selected two points along a fiber, with 200 m measurement range, 8 cm spatial resolution, and 1,000 points/s measurement speed of random accessibility.
