Paper Abstract

Because of a series of advantages such as high sensitivity, non-contact measurement, interferometric vibration sensors have attracted interest from a lot of researchers in vibration sensing field. In this paper, a novel Mach-Zehnder interferomtric vibration sensor which utilizes quadrature detection technology is proposed. In our system, non-polarized light source and 1/4 wave plate is used to obtain two in-phase and quadrature-phase (I/Q) signals. Compared with previous methods, this sensor system has a simple optical configuration and more reliable stability. Theoretical analysis indicates that this sensor can measure the vibration displacement accurately.
