Method of objectively evaluating a surface mark

摘要

A method of objectively evaluating a surface mark provides an objective test methodology for the optical quantification of surface marks. The method may include the steps of reproducibly producing a surface mark on an object and optically evaluating the surface mark. The surface mark may be reproducibly produced by loading a stylus, contacting a surface on the object with the loaded stylus and moving the object and the surface thereon relative to the loaded stylus so as to thereby produce a mark on the surface. Any surface mark is optically evaluated by optically producing images of the surface mark, electronically capturing the optically produced images and measuring selected parameters of the captured optically produced images.
