Abstract

The application of Fabry-Perot (FP) system for vibration sensing is theoretically analyzed and successfully demonstrated by simulation. The separation between the reflecting mirrors of the FP is varying in accordance with the sensed vibration that is in contact with the freely movable mirror. The variable separation is modeled as a small uniform sinusoidal perturbation that satisfies the constructive multiple beam interference inside the cavity. The variation of the separation between the two mirrors of the FP induces a phase variation to the reflected laser beam employed in the system. The constructed signals by signals processing and transformation reveal the effectiveness of the method for vibration sensing and hence the applicability for gravitational and seismic waves monitoring.
