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 …

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

A direct image of an exoplanet system is a snapshot of the planets and disk around a central
star. We can estimate the orbit of a planet from a time series of images, and we can estimate …

This paper presents the first on-sky demonstration of speckle nulling, which was achieved at
the Subaru Telescope in the context of the Subaru Coronagraphic Extreme Adaptive Optics …

The Advanced Technology Large-Aperture Space Telescope (ATLAST) is a concept for an 8-
to 16-m ultraviolet optical near infrared space observatory for launch in the 2025 to 2030 …

We present a new method to achieve high-contrast images using segmented and/or on-axis
telescopes. Our approach relies on using two sequential deformable mirrors (DMs) to …

The Wide-Field Infrared Survey Telescope (WFIRST) is a NASA observatory concept, now in
phase A study, which is designed to perform wide-field imaging and slitless spectroscopic …

High-contrast imaging instruments are now being equipped with integral field spectrographs
(IFSs) to facilitate the detection and characterization of faint substellar companions …

The Subaru Coronagraphic Extreme-AO (SCExAO) system is designed for high contrast
coronagraphic imaging at small angular separations, and is scheduled to see first light on …

Direct imaging of extra-solar planets is now a reality with the deployment and
commissioning of the first generation of specialized ground-based instruments (GPI …
