| Abstract: | Movement of a surface profile is measured with a two-grating interferometer using sinusoidal phase-modulation.Interference patterns which are caused by the movement of an object are captured.By computed the phase,the surface profile of an object is recovered.The result shows that this optical system not only is high accurate but also can measure the 2-D surface profile of an object. |
