摘要
提出了利用单张双曝光全息图通过纵向多重再现,分析局域平均光强的变化,确定无限条纹干涉级数极值特性.并将该方法成功地应用于超音速叶栅流场全息干涉图的判读.
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.
