Toward the objective to control not only the size of crystals but also their shape, it is necessary to observe its evolution process as a basis for understanding and modeling the underlying growth kinetics. Online microscopy provides 2D projections of 3D crystal shapes. In this paper, we present a technique to reconstruct the original 3D shapes from measured 2D projections of KDP crystals. The algorithm requires the projection to be bounded by a convex polygon with six or eight vertices. Numerical results are presented both for synthetic data as well as for experimental data. They show a good agreement between true and estimated values both for highly accurate as well as perturbed projections.en0009-250920166174CrystallizationImagingMonitoringParticle shapeParticulate processesMathematikJournal Article10.1016/j.ces.2015.09.020Other
