DISTRIBUTED FIBRE-OPTIC SENSOR Russian patent published in 2013 - IPC G01B11/16 G01K11/32 G01D5/353 

Abstract RU 2482449 C2

FIELD: physics.

SUBSTANCE: device measures frequency shift during Brillouin-Mandelstam scattering and Rayleigh scattering, caused by deformation and temperature in optical fibre, according to which the device calculates deformation and temperature in the optical fibre.

EFFECT: measuring deformation and temperature simultaneously and independently with high spatial resolution.
