High Contrast Imaging Testbed

Better than 10⁻⁹ contrast on JPL's HCIT for TPF and Eclipse.

Where

JPL High Contrast Imaging Testbed

Programmes

Terrestrial Planet Finder; Eclipse studies

Result

Contrast of about 5×10⁻¹⁰, monochromatic

For the Terrestrial Planet Finder and Eclipse studies, Chris ran experiments on JPL's High Contrast Imaging Testbed and reached a contrast of about 5×10⁻¹⁰ in monochromatic light. He also invented wavefront-control algorithms for space coronagraphy aimed at exoplanet detection.
