Guidestar-Free Adaptive Optics with Asymmetric Apertures
SessionComputational Photography
DescriptionWe introduce and demonstrate the first closed-loop adaptive optics system capable of optically correcting aberrations in real-time without a guidestar or a wavefront sensor. We enable these capabilities by combining asymmetric apertures, machine learning–based PSF estimation and phase retrieval algorithms, and a high resolution spatial light modulator.
