Moiré methods are a versatile set of techniques for in-plane and out-of-plane displacement and deformation measurement, topographic and shape determination, and slope and curvature contouring. The basis of these moire methods are gratings. Deformation of the specimen cause distortions in the grating lines. Visualization of these distortions are enhanced using the moire effect that is achieved by superposing the deformed specimen grating on a reference grating representing the undeformed state of the specimen.
