Paper Abstract

In a previous paper we have described that some dark shadow areas appeared among the interference fringes in real-time holographic interferometry and we pointed that the appearing of these dark shadow regions are the phenomena of caustic in Geometry Optics. These dark shadow region bears certain relation with the interference fringes. The quantitative relation between caustics and real-time holographic interferometry in the experiments of mode I crack and mode III crack were studied in detail. The quantitative relation introduced theoretically in this paper and compare with mode II crack. Based on these relations, holographic method and caustic method can be combined together in interferometry and it can be used as a powerful tool for scientific study and might lead to a wide application in many fields.
