I have generated a simulated light fields of a distant scene imaged by a hypothetical light-field capture system through volumetric turbulence over a long horizontal path. Imaging scenes in this way allows for single-shot scene reconstruction using Multi-Frame Blind Deconvolution (MFBD) where different angular views are substituted for the frames. In this work, I examine the MFBD estimated Point Spread Function (PSF), parameterized in terms of Zernike polynomials, for each of the angular viewpoints. The aim being to understand the degree to which different angular viewpoints are correlated and the rate of decorrelation. The latter rate being important in the design of light-field capture systems designed specifically to deal with extreme anisoplanatism. I find that rate of angular decorrelation is qualitatively very rapid allowing resulting in MFBD reconstructions that are equivalent to fifteen or more independent frames from a single light-field.
