The sample part has surface dimensions of 15 by 15 mm^2, using a random scan pattern. The three files are scanned by the white light interferometer (Zygo NewView 8200 ), ultra-high-resolution structured light 3D scanner (SLS) (customized), and professional SLS (HP 3D STRUCTURED LIGHT SCANNER PRO S3). The spatial resolutions are 2 microns, 5 microns, and 48 microns, respectively. The scanning times are 10hrs, 4 seconds, and 4 seconds, respectively.
