In this study, the 3D reconstruction of programmable rough particles was performed using a Digital Micromirror Device (DMD), with the error-reduction algorithm for 2D shape reconstructions and filtered back-projection for 3D tomographic reconstruction.
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. (C) 2022 Elsevier Ltd.
