Paper Abstract

Miniaturisation of endoscopes can be achieved using lensless endoscope probes, which enhances in vivo deep- tissue imaging technology. The necessity of a detailed understanding of light propagation through optical fibres is paramount, since beam focusing and scanning at tissue require beam shaping at the proximal end of the fibre. For stable light delivery and collection, the sensitivity of various fibre profiles against fibre deformations needs to be reviewed. We present a numerical simulation tool investigating optical field propagation through multimode and multicore optical fibres, emphasizing fibre-bending deformations. The simulation tool enables user to choose optimum fibre with best possible realistic parameters for any application.
