Paper Abstract

A new modified moiré interferometry for measuring u, v, and w displacement fields is proposed. The method is actually integrated with in-plane moiré interferometry and a new interferometry that can attain out-of-plane displacements. The sensitivity of the measurement of the out-of-plane displacement is as high as a half-wavelength of the illuminating light. The measured in-plane and out-of-plane displacement fields are mutually independent and definitely defined.
