Dynamic Deformation Measurement of Specular Surface with Deflectometry and Speckle Digital Image Correlation
The deformation measurement of a specular surface is of great importance during the quality inspection and installation of optical elements or wafers, especially those with large apertures. We propose a deflectometry method with speckle digital image correlation (DeSDIC) to realize the dynamic and h...
