It is critical to carefully examine system vibration in the industry since high vibration levels can lead to costly operational disruptions and equipment failures. This article proposed a Mach-Zehnder interferometer (MZI) and an innovative algorithm to accurately capture and measure vibrations in electromechanical equipment. A vision algorithm is employed to determine the dynamic displacement of a vibrating motor via interferogram. This study provides a novel approach to using interferograms to measure an electromechanical device's vibration (real-time displacement) through an image processing algorithm. The phase-unwrapping method was employed to calculate the vibration amplitude of the corresponding position in each interferogram. Then, the static positions reflected in the optical path variations were accurately extracted via the residue phase least-squares method. For consistency measurement, the camera's frame rate was twice the vibration frequency, and Gaussian filters were applied to enhance the contrast of the interferograms. The proposed method was verified by simulating a theoretical model of the vibrating motor in MATLAB Simulink. The simulation results validate the experimental ones, demonstrating the MZI's effectiveness and the algorithm's accuracy in detecting and measuring vibrations. The proposed interferometer and algorithm offer a novel and practical solution for monitoring real-time displacement in electromechanical equipment and improving operational safety in industrial environments. © 2025 SPIE.
