Brillouin optical correlation domain analysis (BOCDA) in linear configuration is demonstrated newly based on differential lock-in detection. Three-fold enhancement in the spatial resolution is achieved compared to the former system based on beat-lock-in detection, as well as the simpler configuration for the signal processing. Distributed strain measurement over a 57-m test fiber with a 10-cm spatial resolution is presented as a proof-of concept.
