| Abstract: | The modulating effect of holographic plate motion on recorded beams and its influence on the measured results have been studied in this paper. A mathematical expression of the intensity distribution of double exposure-fringe pattern with recorded beams modulated by the holographic plate motion is derived. Based on theoretical investigation of the modulated fringe formation, the holographic analytical method of three dimensional displacements of a measured object when the plate motion exists is proposed. The displacements of the plate are determined by means of a reference object. |
