“…Hence, its applicability is restricted to laboratory environments, and not for common practical use. Multiple video cameras are used to build passive tomography system to measure turbulence strength of the invisible fluid [19]. Underwater cameras are often suffer from the distortion caused by random waves in the water-air interface.…”

“…We give here the essence in brief, while the proofs and full details can be found in our article. 18 For a wide-angle radiating source (a point source), models established in the literature 4, 19 express the variance σ 2 AOA of the AOA by integration along the LOS. Let f be the focal length of the camera.…”

Random distortions naturally affect images taken through atmospheric turbulence or wavy water. They pose new 3D recovery problems. Distortions are caused by the volumetric field of turbulent air or the 3D shape of water waves. We show methods that recover these 3D distorting media. Moreover, it is possible to triangulate objects beyond the refracting medium. Applications include sensing and study of random refractive media in nature, and enhanced imaging including possibilities for a virtual periscope.
