    Abstract

    One key problem of fringe projection techniques for 3D shape measurements is the limited phase unambiguity range when only one grating period is used. Dual-frequency patterns in which involves two grating periods can easily extend the unambiguity range. A method to fabricate accurate dual-frequency patterns is presented. The advantage of using digital dual-frequency patterns for projected fringe profilometry are (1) high geometrical accuracy (< 0.5μm); (2) high contrast ratio; (3) very low high order harmonic distortions; and (4) extended unambiguity range.
