Abstract
The paper focuses on the moire phenomenon as a tool of experimental mechanics. The properties of moire patterns are outlined. The application of these properties to the measurement of displacements of the points of a surface (intrinsic moire), contours or deflections (projection moire) and slopes (reflection moire) is discussed. Observation methods, recording methods, data-processing techniques are outlined and practical aspects are stressed. Sensitivities and precisions that have been achieved are reviewed. Finally, some typical applications to problems in areas of interest are briefly described.
