The linear gauging range can increase to about 8μm, and reduce the angle tilt effectively to the displacement signal, promotes the interpretability for different azimuth. The new design form can obtain in the application scans the side the surface profile, and be possible to unifies optical pick-up head gauging system into the atomic force microscope used in surveying the displacement and the tilt angle of the cantilever, besides has the fine resolution, the structure is also very exquisite, and the low in price, may promote the entire gauging system''s accuracy in the future along with the performance evolution of the optical pick-up head.
