THE APPLICATION OF FOURIER TRANSFORM IN REGULARIZED SPECKLE PHOTOGRAPHY

Zhang Yuanpeng Zhu Huaning Zhou Wenling Liu Hefei (Department of Mechanics,Peking University,Beijing 100871,China)  
Two speckle patterns are recorded using a video camera corresponding to undisplaced and displaced states intn the memory of a computer.After one pattern is added to another,the displacement of the measured points can be calculated by using the Fourier transform.The expression of displacement field is deduced tbr non-uniform displacement,and as an example,a rotatanle disc is tested for illustration.The re- sults prove that the present method is promising.
