Abstract
Moire interferometry is used to measure in-plane displacements, U and V, on flat surfaces. It extends the sensitivity of moire methods into the subwave-length range, making it suitable for the analysis of localized deformations of structural composites. The method is characterized by a remarkable set of qualities: it is a whole-field and real-time method, and it provides high sensitivity, excellent fringe contrast, high spatial resolution and extensive range. Moire interferometry nicely fills the gap between capabilities of other experimental techniques, inasmuch as it can be used in zones of very high strain gradients and it can be used to determine shear strains as readily as normal strains.
