Abstract

The quality of an image transmitted by a multicore, multimode fiber bundle has been investigated. The influence of the limiting factors such as the spatial sampling of the bundle, the cross-talk between each core and the radiative modes in the intercore space has been determined. Two different methods to determine the MTF are compared. The analysis of the data obtained experimentally for the coupling coefficients between fiber cores suggest that two different mechanisms must be invoked to explain the degradation of the image transmitted through the fiber bundle: the cross-talk and the leaky modes.
