Abstract
We propose and experimentally demonstrate the enhancement in the spatial resolution and the dynamic range of Brillouin optical correlation domain analysis by optimized differential lock-in detection. The spatial resolution is improved by more than five times compared to that of ordinary BOCDA with large extension of the dynamic range.
