Abstract

A compact tip-reflection fiber-optic vibration sensing system that uses a lateral-offset tilted fiber grating (TFBG) as sensor head and a vertical-cavity surface-emitting laser (VCSEL) as light source has been demonstrated. Dynamic mechanical vibration measurement up to 200 Hz with signal to-noise ratio better than 40 dB has been achieved.
