Fig. 1. Distribution of Brillouin gain spectra measured by the long-range chaotic BOCDA system. The figure demonstrates the successful detection of a 10-cm-long strained section located near the distal end of a 27.54-km-long sensing fiber. Remarkably, the system achieves an exceptional spatial resolution of 2.69 cm, resulting in an impressive number of effective resolving points reaching 1,020,000. Figure adapted from Ref. 12.
