Abstract

We present a discussion on how an area-encoded fringe pattern is applied to describe the 3D shape of complex objects that have spatially isolated surfaces or large depth continuities. Compared with conventional fringe projection techniques, the proposed scheme is relatively reliable and robust to identify the fringe order. Only one phase measurement is required. This makes it possible to analyze dynamic objects.
