摘要

在这项研究中，我们利用环芯光纤（RCF）架构中的衍射深度神经网络（D2NN），提出了一种全光学图像重建技术。采用轨道角动量（OAM）模式促进成像传输。我们通过实验验证了我们的方法在 1550 nm 工作波长下通过多模光纤（MMF）和 RCF 进行复杂场衍射图像重建的功效。实验结果表明，所提出的方法在缓解 RCF 散射到复原转换问题方面性能优越，明显优于传统的基于 MMF 的成像校正技术。

All-optical image transmission through a dynamically perturbed multimode fiber and a ring-core fiber using diffractive deep neural networks.

In this study, we present an all-optical image reconstruction technique leveraging a diffractive deep neural network (D2NN) within a ring-core fiber (RCF) architecture. Orbital angular momentum (OAM) modes are employed to facilitate imaging transmission. We experimentally validate the efficacy of our approach for complex field diffractive image reconstruction through a multimode fiber (MMF) and RCF at a 1550 nm operating wavelength. The experimental results demonstrate the superior performance of the proposed method in mitigating RCF scattering-to-restoration transformation issues, significantly outperforming traditional MMF-based imaging correction techniques.
