| Abstract: | Based on the analysis of the change of local average inten- sity by means of a single dual exposure hologram and its longitudinal multiple reconstruction,a new method for determining the property of extreme value of the order of infinite interference fringes is reported.This method is successfully applied on criticizing the holographic infinite inter- ference diagram of the supersonic cascade flow field. |
