Abstract
The recovered object in sheared beam imaging is an accumulated average of instantaneous "speckled" image frames. Atmospheric perturbations cause a random tilt in the phase of the return speckle pattern. This tilt induces a random translation in each reconstructed image. This random misregistration of individual frames with respect to each other degrades image quality by blurring the average resultant image.
