Abstract

An optical fiber sensor for vibration monitoring in high power electric plants is presented. The sensor uses an elastic cantilever as transducer, the motion of which is detected by a fiber-based optical head. Vibration measurements up to 250 p.m of peak amplitude, at the 100 Hz fixed frequency are performed, with an accuracy of 0.1 pm and a linearity error within 3%.
