Paper Abstract

Based on the statistical optics, the mechanism and principle of the dual-beam speckle interferometry are studied, and it's mathematical expression of frequency distribution is derived. The experiment shows an agreeable result with the theoretical analysis. The research shows that both the speckle photography and interference fringes exist in the dual-beam speckle pattern.The only interference fringe remains still as the filtering aperture moves. Besides, the interference fringe appears first, is gradually concentrated in pace with adding the load on a sample, and disappears lastly with the photography fringe at the same time.
