摘要
给出了一个测量物体刚体位移的数字白光散斑照相术。数字傅里叶交换从双曝光数字白光散斑图用来产生杨氏条纹。该杨氏条纹能够用数字傅里叶变换结合条纹重构进行自动分析。此外，给出一种条纹质量增强的方法。
This peper presents a method for measuring rigid body motion by white light digital speckle photography. Instead of using laser beam to generate the Young's fringe pattern from a specklegram as conventional speckle photography, a digital Fourier transformation is employed yield the Young's fringe pattern from whiCh rigid they motion can be computed by a new FFT phase shift method. Moreover, a new technique for improving the quality of the Young's fringe pattern is given. Theory together with experiment is demonstrated.
