Abstract: Firstly, a Rockwell diamond indenter tip is tested at different angles and positions by using a scanning white light interferometer, and several image data are obtained. Then, these data are merged together to form the associated geometrical topography with the image stitching method. Moreover, both the tip radius and the cone angle can be obtained with the least-squares Gauss-Newton sphere and cone fitting algorithm. Its validity is demonstrated.
