Geometric moire is a classical optical experimental technique used for full-field, non-contact measurement of displacements and strains. Geometric moire has been overshadowed by finite element method over the past three decades. However, new developments and applications, such as low-cost dynamic double exposure moire, moire applications in stereolitography, etc., have revived the use of experimental geometric moire. A number of new significant questions appear when time-average geometric moire techniques are being applied for scientific and engineering problems. Digital image processing, mathematical and statistical analysis, special numerical methods and elements of chaos theory help to extend the limits of optical experimental time-average moire techniques. Time-average stochastic moire, time-average super-moire, applicability of time-average geometric moire for chaotic oscillations, new quadrature rules for the construction of time-averaged moire fringes in real time mode are main results presented in this book. It will be useful for graduate students, researchers and scientists working in the areas of modeling and applications of geometric moire.
