Paper Abstract

The reflectional display method for information extracting by the speckle pattern is presented in this paper. Combining objective speckle and reflection holography, this method reduces the restriction to optical density of the film. Two applications are presented: the in-. displacement of a specimen of the three point curved bean of coiplex material and the homogeneous degree of deformation of the bearing cap of top motor under axial load are measured respectively by the objective speckle and reflection holography..
