【Abstract】 A 3D surface profile measuring method applying the shadow Moire fringe technique in combination with the phase measuring technique is presented. The grating’s position is controlled by a phase shifter made of electromagnets and precision components to realize the accurate phase shifting, and the 3-step phase shifting process is applied to demodulate the phases of Moire fringes acquired by a CCD camera. The automatic measurement of 3D surface profiles can be carried out by this method with high speed and high precision.更多还原
