Temperature sensor and mechanical deformation in fiber optic Brillouin and Raman scattering via the effects of stimulated

摘要

Invention patent b "temperature sensor and mechanical deformation in fiber optic Brillouin and Raman scattering via the effects of stimulated" d .Is this a system u00f3pto - mouse, using the known effects and stimulated Raman scattering and stimulated Brillouin.For the implementation of measures distributed temperature and mechanical deformation, at the same time, along optical fibres, which are physically adhered to, or embedded.In mechanical structures or materials such as metals, concrete, composite, etc.We propose the use of planar windings of fiber optics to increase the resolution of the measures and define spatially some regions sensing along the optical fiber used as the meIO system sensor measures. It is also proposed to measure any physical quantities which results in deformation mechanics and / or temperature variation along the length of the sensor element of the system.Finally, it is improvement of the system of measures on its module of detection.Where is the proposal to use directional couplers divisors of wave length; as to the spatial resolution of the measures.Where is proposed improvements in the module of generation of pulses from the laser pumping Raman and Brillouin scattering effects stimulated; and, finally,As for the electronics used to carry out the measures, which is a integration of such equipment,Resulting in only one equipment specially designed for the system.
