Abstract
Fabrication of various digital fringe patterns, such as digital sinusoidal gratings, two-dimensional fringe patterns, and two-frequency fringe patterns is presented. The advantage of using various digital patterns instead of other traditional patterns for projected fringe profilometry are (1) high geometrical accuracy (<0.5μm); (2) high contrast ratio; and (3) very low high order harmonic distortions.
