While offering superior spatial resolution, typically limited by either the detector pixel size or numerical aperture ... WebAug 20, 2024 · 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 …
