A reliable method for quantitative detection of weak scratches is proposed based on scratch segmentation and connection of broken scratches. The DWMLD method is used to segment
Surface imperfections (optics)
Surface imperfections on optical surfaces such as lenses or mirrors, can be caused during the manufacturing of the part or handling. These imperfections are part of the surface and cannot be removed by cleaning. Surface quality is characterized either by the American military standard notation (eg "60-40") or by specifying RMS (root mean square) roughness (eg "0.3 nm RMS"). American notation focuses on how visible su
