Abstract
In 2009 our group started the integration of the SCExAO project, a highly flexible, open platform for high contrast imaging at the highest angular resolution, inserted between the coronagraphic imaging camera HiCIAO and the 188-actuator AO system of Subaru. In its first version, SCExAO combines a MEMS-based wavefront control system feeding a high performance PIAA-based coronagraph. This paper presents some of the images obtained during the first engineering observations conducted with SCExAO in 2011: diffraction limited imaging in the visible as well as PIAA coronagraphy in the near infrared; along with the wavefront control strategies to be tested on sky during the next round of SCExAO observations, scheduled in the Fall 2012.
