dc.description.abstractThe NEW EARTH Laboratory (NRC Extreme Wavefront control for Exoplanet Adaptive optics Research Topics at Herzberg) has recently been completed at NRC in Victoria. NEW EARTH is the first Canadian test-bed dedicated to high-contrast imaging. The bench optical design allows a wide range of applications that could require turbulent phase screens, segmented pupils, or custom coronagraphic masks. Super-polished off-axis parabolas are implemented to minimize optical aberrations, in addition to a 468-actuator ALPAO deformable mirror and a Shack Hartmann WFS. The laboratory's immediate goal is to validate the Fast Atmospheric Self-coherent camera Technique (FAST). The first results of this technique obtained in the NEW EARTH laboratory with a Tilt-Gaussian-Vortex focal plane mask, a reflective Lyot stop and Coherent Differential Imaging are encouraging. Future work will be aimed at expanding this technique to broader wavebands in the context of extremely large telescopes and at visible bands for space-based observatories.
