High‐quality signal transmission and imaging through a multimode fiber is essential for optical communications and medical endoscopic imaging, as it can provide high fidelity of the transferred information. Multiple mode superposition and mode coupling distort the incident wave, and a speckle pattern formed at the exit end of a multimode fiber makes the reconstruction of the original object challenging. The transmission matrix method is proposed to characterize the complex mesoscopic optical transmission channels, allowing light to traverse through the random medium. Here, a novel approach, namely polarization‐enhanced parametric speckle imaging, is proposed to improve imaging quality through a multimode fiber by utilizing the properties of polarization evolution through a multimode fiber. The demonstrated superior performance of polarization‐enhanced parametric speckle imaging opens novel avenues for optical communication system and photonics‐based endoscopic diagnosis.

通过偏振增强的参数散斑成像通过多模光纤进行高保真图像重建

通过多模光纤进行高质量的信号传输和成像对于光通信和医学内窥镜成像至关重要，因为它可以提供所传输信息的高保真度。多模叠加和模式耦合会使入射波失真，并且在多模光纤的出口端形成的散斑图样使原始对象的重建面临挑战。提出了一种传输矩阵方法来表征复杂的介观光学传输通道，从而允许光穿过随机介质。在这里，提出了一种新颖的方法，即偏振增强参量斑点成像，以利用多模光纤的偏振演化特性来提高多模光纤的成像质量。
