摘　　要：本文在分析了全息图记录的物理本质后，指出只有用参考光和参考光的逆共轭光作再现光时，才能准确再现原物体的像。其它情况下再现像的畸变是不可被免的。这是由于再现时的波像差所引起。为了把波像差的影响减少至最小，我们建议使用平行光做参考光，并用逆光路再现母全息图。文章还提供了拍摄反射全息图和模压全息图的二步法拍摄光路。并指出在全息干涉计量和轮廓测量中，也应充分注意到波像差的影响。By analyzing the innate character of holographic record,this paper points out the image of the original object is exactly reconstructed only when the reconstructing light is the reference light and inverse reference light.Otherwise the distortion of reconstructing image emerges,and it came from the wave aberration.In order to decrease the wave aberration,we propose to use the parallel light as reference light,and reconstruct the master hologram by using the inverse light road. In this paper,we also gives out the light road of two steps making method for reflecting and embossing holograms.points out the influence of the wave aberration for holographic interfermetry and 3D shape measurement.
