Abstract

Imaging extra-solar planets requires exceptional dynamic range detection. Extreme adaptive optics and coronagraphy improve the planet-to-star intensity ratio, but residual atmospheric speckles still dominate the field of view. We were able to reduce this clutter by removing redundancies in the imaging optics.
