Abstract
Moire contouring techniques provide a rapid means of producing a full-field contour or depth map of a given surface. When used in combination with CCD cameras, digital image processing, and mathematical analysis, a powerful measurement tool emerges. The use of this technology allows rapid quantification of surface shapes, features, and geometry. Corrosion measurement is sorely lacking a suitable measurement tool. Current methods are highly qualitative and operator-dependent. Moire systems provide an excellent solution, producing quantifiable, operator-independent results.
