Paper Abstract

A fiber-optic multiple sensor is presented which is addressed for application in the wiring of high-power electric generators. The simultaneous and independent measurement of temperature and vibration amplitude at 100 Hz is obtained by means of a single sensor. The probe is based on a fiber-optic proximity sensor which detects the light intensity modulation induced by an elastic transducer. The nonlinear region of the optical-head response is exploited, together with appropriate signal processing, so as to obtain intrinsically down-lead insensitive sensor-output.
