Abstract

Coherent imaging through optical multimode fiber has the potential to enable label-free imaging through hair-thin imaging probes deep inside tissues and organs. Towards this goal, we developed a method to efficiently measure the multispectral transmission matrix of multimode fiber. Combined with a computational approach that circumvents the need for active wavefront shaping, this enabled tomographic imaging with confocal and coherence-gating through multimode fiber. Together with the development of retrieving the transmission matrix of dynamically bent fiber and compressing the measurements required for image reconstruction, these efforts address critical challenges towards the realization of practical multimode fiber imaging.
