Researchers have developed a novel adaptive optics (AO) system that can correct optical aberrations in real-time without the need for a guidestar or wavefront sensor. This system leverages asymmetric apertures, a technique previously shown to enable computational phase retrieval, combined with machine learning algorithms. The approach estimates the point-spread function from natural scene measurements and reconstructs phase aberrations, which are then optically corrected. Experimental validation on natural scenes demonstrated superior performance compared to existing guidestar-free methods, requiring significantly fewer measurements and less computation. AI
IMPACT This research could lead to more efficient and less computationally intensive optical correction systems, potentially impacting fields that rely on high-resolution imaging.
