单模多模光纤由于可以通过多种空间模式直接传输图像而被认为是内窥镜成像的理想光学元件。然而，由模式色散引起的波失真一直是一个基本的限制。在这封信中，我们提出了一种方法，用于消除模式色散的影响，从而实现了宽视场内窥镜成像，仅使用一个单一的多模光纤，没有扫描器连接到光纤。我们的方法将有可能彻底改变包括医学和工业在内的各个领域的内窥镜检查。
A single multimode fiber has been considered an ideal optical element for endoscopic imaging due to the possibility of the direct image transmission via multiple spatial modes. However, the wave distortion induced by the mode dispersion has been a fundamental limitation. In this Letter, we proposed a method for eliminating the effect of the mode dispersion and therefore realized wide-field endoscopic imaging by using only a single multimode fiber with no scanner attached to the fiber. Our method will potentially revolutionize endoscopy in various fields encompassing medicine and industry.
