Imaging and pattern projection through multicore fibers using the memory effect

It is possible to focus coherent light through a multicore fiber with a resolution finer than the core-to-core spacing using digital phase conjugation. In this paper we use the memory effect and show that the displacement of the focus spot can be realized simply by tilting the beam incident on the multicore fiber. We demonstrate high-resolution imaging and pattern projection with a calibration procedure consisting of the acquisition of a single digital hologram.
