Abstract
We demonstrate the use of phase-space (e.g. light field) imaging for 3D localization of multiple point sources inside scattering material. The effect of scattering is to spread angular (spatial frequency) information, which can be modeled by a multi-slice forward model in phase space. We propose a sparsity-constrained atomic norm reconstruction algorithm in order to further constrain the problem. By using 4D measurements for 3D reconstruction, the dimensionality mismatch provides significant robustness to multiple scattering effects, with either static or dynamic diffusers.
