Abstract

A concept to achieve high dynamic range images from the ground is presented. The main idea is to calibrate turbulent fluctuations of wavefronts in a telescope pupil with a fibered fully redundant aperture mask. This is the principle of the FIRST instrument whose first prototype version is to see stellar photons in July 2010 at Lick Observatory. Lab results and hopefully first sky results will be presented.
