Abstract

The sensitivity of the dynamic white light speckle method is analysed by the concept of the frequency spectrum analysis of the incoherent imaging system and the method of increasing its sensitivity is presented in this paper, If a photoelastic material is taken as the specimen, the dynamic isochromate patterns are obtained under the same load at the same time Therefore the stress and strain of the structure are solved,
