Abstract

We study the tomographic problem of reconstructing particle volume functions in experimental fluid dynamics from the general viewpoint of compressed sensing, which is a central theme of current research in applied mathematics. The probability of exact reconstructions from few projections is studied empirically and shown to resemble provable results for idealized mathematical measurement setups. Application of our reconstruction algorithm to noisy projections outperforms the state-of-the-art both with respect to accuracy and runtime.
