【 摘 要 】

The Error-Reduction algorithm is tested to reconstruct the exact 2D-shape of irregular rough particles from their experimental interferometric images. The particles tested are programmableparticles generated with a digital micromirror device. The method is first applied to centrosymmetric particles, and then to non-centrosymmetric particles where the twin image problem brings additional difficulty.
