Surface finish, displacement and contour scanner

摘要

A surface finish, displacement and contour scanner is disclosed which effectively protects its stylus from damage even if the stylus meets an obstacle, such as a wall, a major ridge or a crack. The surface finish, displacement and contour scanner further includes a unique transducer designed to provide true displacement transducer operation with or without traverse, a magnetic attach-release mechanism disposed median between the stylus and a transducer, and a ball-and-notch seating structure formed about the point of flexing of the stylus support.
