Abstract

Accurately sensing atmospheric turbulence is vital for optical communications, yet standard methods often obscure the spatial nature of these distortions. Via numerical simulations, the authors show that two-dimensional orbital angular momentum spectroscopy resolves turbulence across radial dimensions, enhancing the accuracy of environmental sensing.
