High Spatial and Spectral Resolution Long-Range Sensing Using Brillouin Echoes

Luc Thévenaz, Stella Foaleng Mafang, Kwang-Yong Song, Sang Hoon Chin, Nikolay Primerov

While classical configurations have a practical spatial resolution of 1 meter, novel approaches have been demonstrated that can overcome this limit to offer spatial resolutions in the centimetre range, while preserving full measurand accuracy. ...

Recent progress towards centimetric spatial resolution in distributed fibre sensing

Luc Thévenaz, Stella Foaleng Mafang, Kwang-Yong Song, Sang Hoon Chin, Nikolay Primerov

Optical fibre sensors based on stimulated Brillouin scattering have now clearly demonstrated their excellent capability for long-range distributed strain and temperature measurements. The fibre is used as sensing element and a value for temperature and/or ...

Time-Domain Distributed Fiber Sensor With 1 cm Spatial Resolution Based on Brillouin Dynamic Grating

Luc Thévenaz, Kwang-Yong Song, Sang Hoon Chin, Nikolay Primerov

We demonstrate an optical time-domain distributed fiber sensor showing the highest spatial resolution ever reported based on Brillouin dynamic grating in a polarization-maintaining fiber. In our scheme, the acoustic gratings containing the information on t ...
