Imaging Theory and Mitigation in Extreme Turbulence-Induced Anisoplanatism
Abstract
The objective of this project was to improve our overall understanding of imaging science in scenarios where the isoplanatic angle is on the order of the diffraction-limit of the imaging system. We also aimed to understand if Light-Field (LF) or plenoptic imaging techniques maybe useful in scene-recovery when turbulence induced distortions are dominated by anisoplanatic effects. We found that for scenes where the ratio of the aperture size to Fried parameter are less than the anisoplanatic error often saturates to a value less than 1 radian squared allowing for scene recovery using traditional post-processing techniques. Also, that in the scenarios LF techniques allow for single-shot (one frame) recovery via post-processing. This final finding hints at the possibility of real-time scene recovery without block-processing and likely allows for simultaneous volume phase recovery.
