Enhancement of the dynamic range in slope-assisted coherent brillouin optical time-domain analysis sensors
We present two techniques that provide an extension of the dynamic range of coherent Brillouin optical time-domain analysis (BOTDA) sensors for dynamic measurements. This type of BOTDA sensors rely on self-heterodyne ... -
Gain dependence of the phase-shift spectra measured in coherent Brillouin optical time-domain analysis sensors
We report on the effects of large pump pulse powers on Brillouin optical time-domain analysis (BOTDA) sensors based on phase-modulated probe wave and coherent self-heterodyne detection. These sensors are particularly ...
