Abstract

Limitations in the densitometric analysis of moire contour patterns have been considered. A fringe analysis method based on heterodyne detection is described. The heterodyne method is shown to be comparatively insensitive to variations in the light-scattering properties of the surface and to allow automatic differentiation between concavity and convexity.
