    Numerical modelling of imaging fibre bundles and their application in optical coherence tomography

    Imaging fibre bundles are widely used in image transmission systems in the visible spectral range1. Their image transmission capabilities and flexibility make them interesting for OCT endoscopy2. However, cross-talk occurring between individual fibres and multimode transmission cause deterioration of the images obtained with OCT systems. In this study, a model of light propagation in a fibre bundle is developed using the Finite Difference - Time Domain (FDTD) method in order to quantify these effects. The simulated bundle output power density distribution is compared to experimental images.
