When it comes to “phase measurement” or “quantitative phase imaging”, many people will
automatically connect them with “laser” and “interferometry”. Indeed, conventional …

Adaptive optics is a prime example of how progress in observational astronomy can be
driven by technological developments. At many observatories it is now considered to be part …

Principles of Adaptive Optics describes the foundations, principles, and applications of
adaptive optics (AO) and its enabling technologies. This leading textbook addresses the …

The Planetary Camera and Spectrograph (PCS) for the Extremely Large Telescope (ELT)
will be dedicated to detecting and characterising nearby exoplanets with sizes from sub …

Abstract The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is a
multipurpose high-contrast imaging platform designed for the discovery and detailed …

Abstract We present the Vortex Image Processing (VIP) library, a python package dedicated
to astronomical high-contrast imaging. Our package relies on the extensive python stack of …

Over the last two decades, several thousand exoplanets have been identified, and their
study has become a high scientific priority. Direct imaging of nearby exoplanets and the …

Conventional imaging systems can only capture light intensity. Meanwhile, the lost phase
information may be critical for a variety of applications such as label-free microscopy and …

Many high-contrast coronagraph designs have recently been proposed. In this paper, their
suitability for direct imaging of extrasolar terrestrial planets is reviewed. We also develop a …

Context. The direct imaging of potentially habitable exoplanets is one prime science case for
the next generation of high contrast imaging instruments on ground-based, extremely large …
