| Abstract: | A new holographic-moire method is presented for acquiring in-plane strain patterns. During the record, double object beams and dual reference beams with orthogonally polarized state are utilized to illuminate the object and the holographic plate, respectively. Two carriers modulated by deformation are introduced by double exposures or in real time. Pure in-plane displacement derivative patterns are obtained after twice filtering. |
