Phase retrieval in multicore fiber bundles

Not Accessible

Abstract

Multicore fiber bundles are widely used in endoscopy due to their miniature size and their direct imaging capabilities. They have recently been used, in combination with spatial light modulators, in various realizations of endoscopy with little or no optics at the distal end. These schemes require characterization of the relative phase offsets between the different cores, typically done using off-axis holography, thus requiring both an interferometric setup and, typically, access to the distal tip. Here we explore the possibility of employing phase retrieval to extract the necessary phase information. We show that in the noise-free case, disordered fiber bundles are superior for phase retrieval over their periodic counterparts, and demonstrate experimentally accurate retrieval of phase information for up to 10 simultaneously illuminated cores. Thus, phase retrieval is presented as a viable alternative for real-time monitoring of phase distortions in multicore fiber bundles.
