Focal-plane wavefront sensing with narrowband light using a short multi-mode fiber
We propose a focal-plane wavefront sensor (FPWFS) based on a short multimode fiber (MMF). By coupling the aberrated focal-plane field into an MMF of length 1 cm, we preserve modal interference over a 10 nm bandwidth at near-infrared wavelengths, but broader bandwidths could be achieved by appropriately tuning the fiber length. The resulting output
