Vibration measurement, observing the holographic interference patterns of vibrating objects in real time in a period of time, is realized with a system, in which a speaker with aluminum foil is used as the vibrating object, imaging is realized with the diffuse reflection light from the raw surface of the aluminum foil, and an optically addressed liquid crystal spatial light modulator is used as the recorder. Time average interference measurement method is used in the experiment, and the vibration interference patterns of the object with different vibrating frequencies is obtained. When the vibrating frequency changes continuously, the changing process of the holographic interference patterns of the object is observed clearly, and the near-real time holographic interference patterns are gained.
