Scanner-free and wide-field endoscopic imaging by using a single multimode optical fiber

Phys Rev Lett. 2012 Nov 16;109(20):203901. doi: 10.1103/PhysRevLett.109.203901. Epub 2012 Nov 12.


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.
