Practical eight-frame algorithms for fringe projection profilometry

Opt Express. 2013 Jan 14;21(1):903-17. doi: 10.1364/OE.21.000903.

Abstract

In this paper we present several eight-frame algorithms for their use in phase shifting profilometry and their application for the analysis of semi-fossilized materials. All algorithms are obtained from a set of two-frame algorithms and designed to compensate common errors such as phase shift detuning and bias errors.
