  • Light field-based beam correction systems and methods
    Patent number: 12140774
    Abstract: An afocal sensor assembly detects a light beam with an aberrated wavefront. The afocal sensor assembly is configured to provide sorted four-dimensional (4D) light field information regarding the light beam, for example, via one or more plenoptic images. Based on the 4D light field information, a lossy reconstruction of an aberrated wavefront for one or more actuators of an adaptive optics (AO) device is performed. The AO device can be controlled based on the lossy reconstruction to correct the wavefront of the light beam. In some embodiments, the aberrated wavefront is due to passage of the light beam through atmospheric turbulence, and the lossy reconstruction and correction using the AO device is performed in less than 1.0 ms. The lossy reconstruction of the aberrated wavefront can have a phase accuracy in a range of ?/2 to ?/30.
