Paper Abstract

By using three noncoplanar coherent laser beams intersecting one another at angles larger than 30° three sets of interferometric grating are generated. By placing a specimen coated with a photosensitive material inside this grating field and exposing to it before and after load three distinctive moire fringe patterns can be obtained, from which principal surface strains can be calculated by using the strain rosette formula.
