Enhancing strain dynamic range of slope-assisted BOTDA by manipulating Brillouin gain spectrum shape

A novel technique for improving the dynamic range of slope-assisted Brillouin optical time domain analysis (SA-BOTDA) is proposed. By modulating the pump pulse with a specially designed signal generated using an arbitrary waveform generator, we may manipulate the shape of Brillouin gain spectrum (BG...
