FIBER-OPTIC DEFORMATION SENSOR Russian patent published in 2006 - IPC G01B11/16 G01D5/353

Abstract RU 2282142 C1

FIELD: measuring technique.

SUBSTANCE: fiber-optic deformation sensor comprises generator of sinusoidal signals that modulates the intensity of laser emitter and spectrum analyzer that is used for determining the resonance frequencies of the signal of back scattering from the measuring converter. The values of the resonance frequencies are related to the mechanical deformation of different zones of the structure that is provided with the measuring converter.

EFFECT: reduced measurement time.
