Abstract
Adaptive optics has been successfully used for decades in the field of astronomy to correct for atmospheric turbulence. A well-developed example involves sensing the slightly distorted wavefronts with a Shack–Hartmann sensor and then correcting them with a phase conjugate device. While the Shack–Hartmann sensor has proven effective for astronomical purposes, it has been less successful for use in deep turbulence conditions often found in ground-to-ground-based optical systems. We have studied an alternative way to sense and correct distorted wavefronts using a plenoptic sensor. We review the design of the plenoptic sensor and directly compare it with the well-known Shack–Hartmann sensor. An experimental comparison of the plenoptic sensor and the Shack–Hartmann sensor is performed to highlight their differences in real-world atmospheric turbulence conditions.
