    A meta-imaging sensor detects an extra-fine 4D light field distribution using a vibrating microlens array, enabling high-resolution 3D photography up to a gigapixel with fast aberration correction, demonstrated on a telescope aimed at the Moon.

    Ground-based telescopes can in principle make high-resolution, wide-field observations when fitted with ground-layer adaptive optics (GLAO). These authors report observations of the core of the globular cluster M3 after a recent upgrade to their GLAO system. In natural seeing of 0.7″, the point spread function at 2.2-µm wavelength was sharpened to 0.3″ over a field of at least 2′. The wide-field resolution was enhanced by a factor of two to three over previous work, and extends to a wavelength of 1.2 ′m.
