将数字实时全息应用于不同孔间距孔洞夹杂物的实验研究,采用计算机数字再现,得到孔间干涉应变场分布的数字全息干涉条纹图。通过对孔洞干涉的条纹级数、形状和,分布情况的分析,证明了数字实时全息方法良好的适用性、重复性和直观可比性。
Digital real-time hologram is used in an experiment study about multi-inclusion of cavity during different cavities' distance. Digital hologram interferometric fringe patterns about strain field' distribution are obtained in computer digital reconstruction. The interferometrie fringes' series,shape and distribution are analysed The potential of applicability, repeatability and intuitive comparability are proved in this method.
