摘　　要：采用错位散斑检测技术对含脱胶缺陷的蜂窝纸板试件进行了无损检测,准确地确定缺陷的位置、形状和缺陷的大小。试验过程显示,此方法具有非接触、实时、快速、灵敏度高、全场等优点,有望成为蜂窝纸板脱胶缺陷的现场检测技术。Shearography was applied to the nondestructive test of facesheet/core delamination in honeycomb paperboard. Test results showed that the location, shape, and size of the defect could be exactly determined. Featured with real time, rapidness, high sensitivity, non-contact and full field measurement, the method has great potential to be an important in--situ measurement technique for honeycomb paperboard.
