Reconstruction performance for image transmission through multimode fibers

Abstract

Due to the applications in the fields of optical communication, neuronal imaging, and medical endoscopic imaging, the study of multimode fiber (MMF) wavefront transmission is crucial for image reconstruction and wavefront generation in user terminals. State of art studies in this area focus on high-quality image reconstruction and wavefront shaping. Besides the way of imaging reconstruction, the performances of image reconstruction and wavefront shaping are also dependent on system and environment parameters. This paper numerically analyzes the influence of key factors, such as the numerical aperture (NA) of the near-end objective lens of the MMF imaging system, the charge coupled device (CCD) noise of the acquired image, and the ambient temperature at close distances. This work would help to the optimization of the MMF-based imaging system and provide a theoretical basis for potential applications in optical communication systems, neuron imaging and endoscopic diagnosis.
