NirvanaVIS at LBT: AO-assisted speckle holography for wide-field visible imaging

High-angular-resolution image reconstruction from ground-based telescopes remains limited by atmospheric tur bulence and by the rapid temporal decorrelation of the speckle pattern. Speckle holography and bispectrum phase retrieval provide efficient post-processing approaches that complement adaptive optics (AO) correct...

METIS high-contrast imaging simulations: from instrument modelling to science readiness

The Mid-infrared Extremely Large Telescope (ELT) Imager and Spectrograph (METIS) instrument, expected to see first light in early 2030, aims to detect and characterise exoplanets and circumstellar disks through high contrast imaging (HCI) and spectroscopy. The High-contrast End-to-End Performance Simulator (HEEPS), ini...
