Abstract
Multimode optical fiber (MMF) based original information transmission faces a great challenge that the information will be scrambled when the fiber is perturbed due to interference between hundreds of modes. Ring core fiber (RCF) supporting a few weakly-coupled mode groups (MGs) of orbital angular momentum (OAM) provides an alternative robust imaging method without strong interference. Moreover, the OAM beam with a helical phase front propagating in RCF has the property of edge enhancement, making a super-resolution Imaging. In this paper, an RCF based robust super-resolution imaging with OAM is presented. We demonstrated the feasibility of the RCF based high-quality imaging system with a set of handwritten digits and compared it to conventional MMF based imaging system with external perturbations. The experimental results show that the RCF based imaging possesses higher resolution and robustness. This scheme may stimulate more research exploiting endoscopic imaging in non-static environments.
