title: Comparison of reference image generation techniques for projection moiré interferometry.
abstract: Three different approaches of generating reference images for projection moiré interferometry are compared. An interpolation-based phase-shift technique that phase shifts the actual reference images is shown to reduce error by over 25% and to reduce processing time compared with the common cosine-wave- and square-wave-based approaches.
