Paper Abstract

A non-contact whole field vibration measuring method, which is based on speckle interferometry theory, is described in this paper. The whole field vibration model with amplitude ranging from zero to several microns can be obtained automatically. The frame update speed is 5 frames per second in our experimental. For demonstration, a round aluminum plate with 100 mm in diameter and 2 mm in thickness, of which the surrounding edge is bonded, is excited by PZT. The vibration model is measured. For the application, the preliminary result of the piezoelectric motor vibration model is described in this paper.
