This poster introduces an algorithm to reconstruct a three dimensional object from its two dimensional projection. It discretizes the problem in a coordinate system given by a priori knowledge of the object’s symmetry. The resulting system of linear equations can be solved in a least squares sense. The method is applied to a strongly interacting Rydberg gas in order to study saturation effects and scaling laws in the excitation dynamics.
