| Abstract: | In this paper, the characteristics of the mode I caustics images from experiments are analyzed according to the theory of caustics method and on the basis of which a criteria is given for the determination of the position of the caustics. Thus a method for the processing of such kind of images on a PC may be put forward basing on this criteria, by which the greatest diameter of the caustics may be distinguished (which is needed for the evalution of the S. I. F. ) automatically with good accuacy. |
