Brillouin optical time-domain analysis sensor with amplification of pump pulses and tolerant to non-local effects
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 ... -
Cost-effective Brillouin optical time-domain analysis sensor using a single optical source and passive optical filtering
We present a simplified configuration for distributed Brillouin optical time-domain analysis sensors that aims to reduce the cost of the sensor by reducing the number of components required for the generation of the two ... -
Gain dependence of measured spectra 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 detection. It is found that the large Brillouin gain that comes ... -
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 ...
