Abstract

This paper proposes a new method for measuring three-dimensional vibrations. By a spherical cooperative target, the system realizes interference from a spherical wave and a plane wave. It solves the problem of complex changes in interference fringes when two spherical waves are used to measure three-dimensional vibration. And the vibration calculation is very simple. Meanwhile, the interferometer integrates two interference arms into a beamsplitter by coating design and can monitor the stability of the system itself. Theoretical analysis and experiment are performed. The experiment results indicate that the method can monitor three-dimensional vibrations accurately.
