Robustness of chaotic-light correlation imaging against turbulence

We consider an imaging scheme, inspired by microscopy, in which both correlation imaging and direct intensity imaging can be performed simultaneously, to investigate the effects of strong turbulence on the two different images. The theoretical comparison between direct and correlation imaging in the presence of strong turbulence unambiguously reveals an advantage of the latter. Remarkably, this advantage, quantified by analyzing the visibility of periodic sample patterns, is more striking when the presence of turbulence becomes the dominant factor in determining the image resolution.
