提出了通过单多模光纤传输复杂像场的方法的理论分析。使用已知的参考图像，我们表明可以评估光纤的瞬时模态色散并使用累积模态相位的知识来恢复物场。为了测量从光纤发出的复杂物体和参考场，我们建议使用两个摄像机的简单布置来记录强度和傅里叶图像，然后使用改进的 Gerchberg-Saxton 算法进行完整的复杂场重建。虽然在这种方法的任何未来实施中仍然可能会遇到一些实验挑战，但我们相信它最终将允许通过长的多模光纤进行首次图像传输。
Theoretical analysis of a method for transmitting a complex image field through a single multimode optical fiber is presented. Using a known reference image, we show that it would be possible to evaluate the instantaneous modal dispersion of the fiber and use the knowledge of accumulated modal phases to recover the object field. For measuring the complex object and reference fields emanating from the fiber, we propose using a simple arrangement of two cameras for recording the intensity and Fourier images, followed by a modified Gerchberg–Saxton algorithm for full complex field reconstruction. While some experimental challenges could still be expected in any future implementation of this approach, we believe it would eventually allow the first image transmission through a long, multimode optical fiber.
