Abstract: In this paper, we describe an optical interferometer applied to 3D inspection of micro-components. The resulting interference fringes that are related to the deformation and surface contour of MEMS-components are analyzed by the fast Fourier transform (FFT) and 3-step phase-shifting algorithms. Experimental results show the feasibility of the proposed method for 3D deformation and surface contour measurement of micro-components.
