Neuromorphic wavefront sensing for high-speed adaptive optics

Wavefront sensing is often the loop speed limiting factor in adaptive optics (AO) implementations. Currently available wavefront sensos rely on the use of high-speed cameras with small temporal resolution, but they often stream data to a buffer limiting the speed of feedback control loops. Neuromorphic cameras respond to changes in intensity, streaming only dynamic information from the scene in an Address-Event Representation format. In this work, we demonstrate the estimation of wavefront slopes utilizing a neuromorphic camera in a Shack-Hartman wavefront sensor configuration integrated in a simple but fast AO control loop.
