Analysis holographic interferogram of links of vibrating system

Abstract

A procedure for calculating the amplitudes of the normal components of the displacement vector in case of three-dimensional vibrations of any point on the surface of mechanical vibrating system is proposed on the basis of experimental holographic interfrometry data and the theory of vibrations of mechanical systems. The analysis of fringe in holographic interferogram is based on several holographic interferogram of the vibrating links of wave mechanical system which are obtained using Time-Average holographic interferometry method.
