Query: Chaotic Brillouin Optical Correlation Domain Analysis   We propose and experimentally demonstrate a chaotic Brillouin optical
correlation-domain analysis (BOCDA) system for distributed fiber sensing. The
utilization of the chaotic laser with low coherent state ensures high spatial
resolution. The experimental results demonstrate a 3.92-cm spatial resolution
over a 906-m measurement range. The uncertainty in the measurement of the local
Brillouin frequency shift is 1.2MHz. The measurement signal-to-noise ratio is
given, which is agreement with the theoretical value.
