剪切散斑干涉技术及应用研究进展
Research progress in shearography and its applications
摘要
Abstract
Shearography is an optical non-destructive measurement method for defects detection without contacting objects.Using this method we can obtain the information of defects by calculating phases of speckle pattern of the object before and after deformations.This technology has been widely used in aerospace and other industrial non-destructive measurement fields.In this paper, we introduce the progress of shearography from two aspects: its key technologies which include various shearing device for achieving a large viewing angle and spatial carrier technology for dynamic measurement, and speckle image processing technology which includes a variety of image processing algorithms.Finally, we describe the domestic and international application of shearography and prospect the development direction on the application of shearography to the dynamic measurement, measurement of smooth surfaces and back-calculation of deformation derivatives for the amount of deformation quantitatively calculated.关键词
