Comment on "Turbulence-free ghost imaging" [Appl. Phys. Lett. 98, 111115 (2011)]
Jeffrey H. Shapiro
TL;DR
This paper clarifies that lensless pseudothermal ghost imaging is affected by atmospheric turbulence, leading to spatial resolution loss, contrary to previous claims of turbulence immunity.
Contribution
It challenges prior assertions by demonstrating that atmospheric turbulence impacts the spatial resolution of ghost imaging.
Findings
Turbulence causes resolution degradation in ghost imaging.
Ghost imaging is not immune to atmospheric effects.
Resolution loss occurs along propagation paths.
Abstract
It is shown that lensless pseudothermal ghost imaging is not immune to spatial resolution loss from the presence of atmospheric turbulence along the propagation paths.
