Cost-effective Brillouin optical time-domain analysis sensor using a single optical source and passive optical filtering
(Hindawi Publishing Corporation, 2016)
Artículo / Artikulua,
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 ...
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 the phase-shift spectra measured in coherent Brillouin optical time-domain analysis sensors
(IEEE, 2016)
Artículo / Artikulua,
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 ...
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 ...
Non-local effects in Brillouin optical time-domain analysis sensors
(MDPI, 2017)
Artículo / Artikulua,
Brillouin optical time-domain analysis (BOTDA) sensors have great potential to provide distributed measurements of temperature and strain over large structures with high spatial resolution and measurement precision. However, ...
