Abstract
This paper described a novel miniaturized polarization-independent fiber-optic interferometer based on a SFOP and its
application in micro-vibration measurement. Firstly, we presented a SFOP which can eliminate the polarization fading
effect. Secondly, we established the hardware system of a novel miniaturized polarization -independent fiber-optic
interferometer. Finally, we analyzed the fitting results of experiment data of micro-vibration measurement. The phase-shift
coefficient / V of PZT is 9.924 rad /V and 10.286rad /V when the voltage changes from 3.0V to 4.8V and from
0.5V to 4.0V, respectively. The error is mainly due to the hysteresis of PZT. The experimental results showed that the
interferometer can be perfectly used to measure the micro-vibration..
