Annular aperture cone glass shearing speckle photographic method for defect measurement

CHEN Bing-quan ( Department of Physics, Suzhou University, Suzhou 215006, China )  
A new method of the defect measurement is proposed by using annular aperture cone glass shearing speckle photography. This is a non-contact method, which is not affected by form and position of the defect, and it can accurately measure the size and form of the defect. After analyzing the basic principle of annular aperture cone glass shearing speckle photography,the analytic formulas of average intensity of light and experimental results are given. The results show that the deformed information of an object in all directions can be recorded simultaneously on one double exposed speckle pattern. And a single speckle pattern can accommodate adequate information to replay the whole dynamic process of an object. During the process of replaying dynamic object, the position of defect doesn’t change with the stripe variety of speckle photograph, while the filter aperture is rotating.
