Abstract
We demonstrate the extension of the measurement range of Brillouin optical time-domain analysis (BOTDA)
sensors using a distributed Brillouin amplifier (DBA). The technique is based on injecting a DBA pump wave in
the fiber to generate an additional Brillouin interaction that amplifies the BOTDA pump pulses. Furthermore,
the differential pulse-width pair method is used to counteract the detrim ...
