Abstract

We evaluate a novel wavefront sensing technique using digital holography. This technique divides the aperture plane into multiple subapertures with a unique digital holographic image created in each subaperture. This reduces the complexity and allows for parallelization of the total wavefront computation. This is a key result, as the associated decrease in the processing latency will increase the available bandwidth of an adaptive optics system. We demonstrate this technique through laboratory testing and show that the wavefront sensor can accurately measure phase degradations on a sample target image.
