Abstract
A single multimode fiber is considered an ideal optical element for endoscopic imaging due to the possibility of 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 propose a method for eliminating the effect of mode dispersion and therefore realize 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.
摘要
单模光纤因其可以通过多个空间模式直接传输图像，被认为是内窥镜成像的理想光学元件。然而，模式色散引起的波失真一直是一个根本性的限制。在本信中，我们提出了一种消除模式色散影响的方法，从而实现了仅使用单根无扫描仪的多模光纤进行广角内窥镜成像。我们的方法有可能彻底改变医学和工业等各个领域的内窥镜技术。
