论文摘要
多模纤维提供了高分辨率和微型化的优势，而小型纤维比光学成像领域的单模式纤维相比。但是，多模纤维的成像易受MMF扰动的影响，这可能导致传输图像中的继发空间畸变。扰动包括纤维中的随机干扰以及环境噪声。在这里，我们利用了切割蛋糕的Hadamard编码算法的快速聚焦能力来抵消扰动的影响并改善系统的鲁棒性。模拟表明，它可以在2000个测量值下接近理论增强。实验结果表明，该算法可以帮助系统在MMF受到干扰的短时间内重新聚焦。这项研究将进一步有助于在医学，通信和检测中使用多模纤维。
Multimode fibres offer the advantages of high resolution and miniaturization over single mode fibers in the field of optical imaging. However, multimode fibre's imaging is susceptible to perturbations of MMF that can lead to secondary spatial distortions in the transmitted image. Perturbations include random disturbances in the fiber as well as environmental noise. Here, we exploit the fast focusing capability of the Cake-Cutting Hadamard coding algorithm to counteract the effects of perturbations and improve the system's robustness. Simulation shows that it can approach the theoretical enhancement at 2000 measurements. Experimental results show that the algorithm can help the system to refocus in a short time when MMFs are perturbed. This research will further contribute to using multimode fibres in medicine, communication, and detection.
