Abstract

In this work, a study for the measurement of a nonspecular object shape by using the fringe pattern projection technique is presented. This study uses only one modulating grating, unlike the moire projection method, which uses two modulating gratings. The proposed method was tested with several objects, and the results will be shown at the end of the presented work. To obtain the modulating phase of the generated fringe patterns, we used step phase shifting algorithms and the Fourier transform method. The obtained results show that the proposed method has an acceptable precision with errors around 0.5%.
