AI Technical Summary
Existing technologies struggle to efficiently separate different types of vortex beams, especially when severe distortion occurs during free-space propagation, leading to a sharp deterioration in separation performance. Furthermore, fixed structures are ill-suited to adapting to parallel separation and dynamic changes of dissimilar modes.
By combining an adaptive optics compensation module and an optical separation module with a CCD detector and a data processing module, parallel separation of the composite vortex beam is achieved through pre-compensation phase and adaptive feedback optimization.
In the presence of phase perturbations, efficient separation of non-homogeneous vortex beams is achieved, improving the demultiplexing capability and communication efficiency of vortex beams for communication while maintaining information integrity.
