孔径位向可调的白光散斑照相

WHITE-LIGHT SPECKLE PHOTOGRAPHY OF THE POSlTlON AND DlRECTION REGULATING OF THE APERTURE

本文报道了孔径位向可调的白光散斑照相法,给出了理论分析和实验证明.该方法能够在一张白光散斑图上记录物体多次变形的信息,在全场滤波分析时,能方便地获得物体各次变形的全场信息.

White-light speckle photography of the position and direction regulating of the aperture is proposed in this paper. The theoretical analysis and experimental verifications are given. This method to record multiple displacement information on a single white-light specklegram. The full-field fringes corresponding to each deformation of an object can be obtained respec-tively by optical filtering.
