Brillouin optical time-domain analysis sensor with amplification of pump pulses and tolerant to non-local effects
(SPIE, 2016)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a simple technique to provide conventional Brillouin optical time-domain analysis sensor with compensation for pump pulse attenuation and tolerance to non-local effects. The technique is based on operating ...
Gain dependence of measured spectra in coherent Brillouin optical time-domain analysis sensors
(SPIE, 2016)
Contribución a congreso / Biltzarrerako ekarpena,
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 detection. It is found that the large Brillouin gain that comes ...
