The Coronagraph Instrument (CGI) is one of two instruments on the
Wide Field Infrared Survey Telescope (WFIRST), a NASA project now
in the design (Phase B) stage and scheduled for launch in 2025.
• CGI is designed to demonstrate space coronagraphy at sensitivity levels
of Jovian-mass planets and faint debris disks in reflected starlight.
• The CGI design is tailored to the predicted WFIRST observatory
characteristics, and design refinements continue as engineering
knowledge of the WFIRST advances.
• The CGI will demonstrate in space, for the first time,
key enabling technologies for future exo-Earth imaging missions:
• precision optical wavefront control with deformable mirrors,
• sensitive EMCCD photon-counting imaging detectors,
• selectable coronagraph observing modes,
• l ow-resolution integral field spectroscopy,
• advanced algorithms for wavefront sensing and control,
• high-fidelity models for the integrated spacecraft and coronagraph,
• and post-processing methods to extract images and spectra.
