The main ones are projectors, optical electron microscopes and optical profilometers. Since this method uses photoelectric and electromagnetic technology, in order to obtain the topographic features and size of a certain structure of the blade / tool, photoelectric or electromagnetic waves must be able to contact the structure without obstacles. If the structure is complex (shielded from light and electromagnetic waves), it is difficult to accurately obtain the geometric data information of the structure, such as deep or complex or small-sized concave structures.
