3D tomographic reconstruction of irregular rough particles from interferometric images

•3D Tomographic reconstruction of irregular rough particles from their interferometric images.•The error-reduction algorithm and the filtered back-projection are used.•Centrosymmetric and non-centrosymmetric particles are tested. Using a Digital Micromirror Device (DMD), the 3D-reconstruction of programmable rough particles (centrosymmetric or non-centrosymmetric) are done from a set of 120 interferometric images. This can be done using the error-reduction (ER) algorithm for the 2D shape reconstructions and the filtered back-projection for the 3D tomographic reconstruction.
