|Abstract:||In this study, we propose an integrated method which combines fringe projection and digital image correlation (DIC) method into one optical system for 3-dimensional displacement measurement. Sinusoidal fringes are projected on an object using a liquid crystal display (LCD) fringe projector. Two sets of images, one containing projected fringes and the other with only white light speckle background, are captured by a CCD camera and processed using DIC to obtain in-plane displacement. Fourier transform is also employed to evaluate the images for out-of-plane displacement. Experimental results are compared with analytic solutions and the results demonstrate that both in-plane and out-ofplane displacements can be accurately measured using the proposed method.|
