Paper Abstract

A novel profilometry---Talbot projection moire topography is demonstrated in this paper, which allows to take 3-D moire measurement under non-dark-room condition while the projecting lens can be eliminated. The moire contours are converted to 3-D data using phase shift methods with an image data processing system. The results of a fundamental experiment and its accuracy analysis are presented also.
