Measurement of scapular kinematics with the moiré fringe projection technique.

The aim of this study was to investigate the applicability of the moiré fringe projection technique (MFPT) to quantify the scapular motions relative to the thorax. This system was composed of a LCD projector, a digital photographic camera, and a microcomputer. To automatically obtain the scapular profiles, the phase shifting method was combined with the MFPT.
