摘要
本文利用旋转孔径散斑照相不同方向的衍射晕携带着物平面不同部位信息的原理,提出了一种新的θ调制方法.实验证明,该方法完全可行有效.
In this paper,we present a new 0 modulation method which isbased on the principle that the diffraction halo of rotating aperture specklephotography in different directions carries informations of different parts onthe object plane.Experiment demonstrates that this method is valid andeffective.
