Airborne three-dimensional cloud tomography
We seek to sense the three dimensional (3D) volumetric distribution of scatterers in a
heterogenous medium. An important case study for such a medium is the atmosphere …

Turbulence-induced 2d correlated image distortion
Due to atmospheric turbulence, light randomly refracts in three dimensions (3D), eventually
entering a camera at a perturbed angle. Each viewed object point thus has a distorted …
