摘要
To provide a method and system for dynamic shearographic inspection.SOLUTION: The dynamic shearographic method allows nondestructive inspection of layered materials, in particular, those including a porous material. The method uses a load profile that increases and decreases the load, for example in a saw-tooth manner, without decreasing the load back down to the initial loading state, usually zero loading. Using the load profile in this manner constantly refreshes the reference speckle images to minimize background noise and allows defects to be distinguished from the noise.SELECTED DRAWING: None
