Accelerometer, angular and linear opto mechanical based on Bragg gratings in optical fibers

摘要

Accelerometer, angular and linear opto mechanical based on optical fiber Bragg gratings in the invention refers to a triaxial accelerometer, angular and linear.Linear and angular accelerations imposed on the accelerometer generates displacement in a seismic mass, which are perceived illuminating optical fibers with Bragg gratings are inscribed and analysing the reflections by means of a processing optical and electronic processing. The seismic mass is fully supported by the optical fibers.In addition, the accelerometer shows the results of the optical processing already scanned and normalized by the power of the spectral ray of light used by sensors.
