“…So eventually, and even with regard to the high accuracy of the AFM, the limited field of assessment and lack of feasibility gave the heavier weight to the use of SEM in this study. The surface of the samples were scanned by SEM using the backscattered electron (BSE) detector and viewed on computer representing the basic 2D topography of the resin composite at 3000x magnification 37 on which Gwyddion 2.53, was used for obtaining the surface roughness parameters from a 3D reconstruction model of surfaces using the SEM (BSED) scans based on stereo-vision concept 2,38 . This newly developed roughness analysing method using SEM scans visualized surface roughness by giving detailed roughness maps, which showed local variations in surface roughness values.…”
