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 Delta phi/Delta V of PZT is 9.924 rad/V and 10.286 rad/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.
