Abstract
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.
