scanning moire topography

A contour mapping technique that uses electronic scanning and sampling techniques instead of a reference grating (see moire topography; projection moire topography) to obtain moire fringes, producing clearer fringes and facilitating distinctions between a depression and an elevation of the object and automatic interpolation of the moire fringes.
