Detection of Scratch on Transparent Plate with Strong Scattering Noise by Digital Holographic Technique

Detection of Scratch on Transparent Plate with Strong Scattering Noise by Digital Holographic Technique

We applied a digital holographic detection technique to detect the scratches on glass surfaces with scattering noise. In the experiment, scratches with widths of 1.67 µm were generated on the front sides of the glass slides, and three different gray levels were painted on the back sides of the glass...
