Abstract
The paper reviews recent contributions to the theory and experimental improvements of moire interferometry. After short reintroduction of the principle some modifications of the optical system to broaden the measurement capabilities are presented. They include real-time differentiation of displacement patterns, three dimensional displacement measurements, configurations for shear strain determination, and new techniques for producing molds of specimen gratings. Separately, the progress in information processing from fringe patterns is presented. Selected aspects of manual and automatic approaches are discussed.
