Transferring optical information in free space with large bandwidth and high transmission capacity has gained significant attention in various applications, such as remote sensing, underwater communication, and medical devices. Nevertheless, unpredictable, unknown phase perturbations or random diffusers within the optical path pose great challenges, limiting the high-fidelity transmission of optical data in free space. Adaptive optics presents a potential solution that can correct for random distortions dynamically; however, spatial light modulators and iterative feedback algorithms employed inevitably increase both cost and complexity.
