摘要
本文在多孔法基础上提出用超多孔光阑装置进行散斑记录。实验结果表明,超多孔法克服了多孔法存在的某些缺点,使位移测量范围扩大,灵敏可调性增加,尤其对模型位移事先不易估计的实验,该方法是行之有效的。
Based on the multi - apertures Photography, the paper discribes that speckles are Photoed by super-multi -apertures Photography The experimental result showsthat this method has advantage overthe original one, has wider range in measuring displacement and increase the change in sensitivity This method is practical in the experiment in which model's displacement is not easily estimated.
