This paper presents a system for measurement of the full field and crack tip properties of a fractured material. The variation of fringes can be obtained from one image processing piece of equipment. The reflection fringes from other image processing equipment can determine the caustic diameter. By comparatively and sequentially observing and evaluating the fringe pattern, we can determine the behavior of crack growth.
