本文着重提出能提高散斑条纹质量的白光散斑照相的信息记录技术以及用几何光学知识推导微小三维位移公式,最后介绍实验验证。
In this paper, the information recording technology of white light speckle photography, which can improve the quality of speckle fringes, and the derivation of the tiny three-dimensional displacement formula with geometrical optics knowledge are put forward emphatically. Finally, the experimental verification is introduced.
