Millimeter-Level-Spatial-Resolution Brillouin Optical Correlation-Domain Analysis Based on Broadband Chaotic Laser

We propose and demonstrate a millimeter-level-spatial-resolution Brillouin optical correlation-domain analysis system based on a broadband chaotic laser, where the spatial resolution only depends on chaotic signal bandwidth. By adjusting the bandwidth of chaos, the single correlation peak has been c...
