The primary objective of this study is to demonstrate the feasibility of measuring 3-D topography of surface abrasion using Fourier transform profilometry(FTP).A new method is introduced to produce the sinusoidal light,and the deformed fringe images on the surface of object are grabbed by CCD camera.Then processed by FTP,the shape three-dimensional topography of abrasion can be recovered.In this application,a surface abrasion under hundred thousand times is used to demonstrate the validity of the method and the experiment results are compared with those obtained from four-step phase shifting.
