Integrated Focal Plane Wavefront Estimating for Space Mission Coronagraphs

As part of the FY17 CIF effort, we have raised the TRL from 1 to 3 having demonstrated the key concept in our solution (See Figure). This method uses an already existing optical element in a coronagraph to provide controlled diversity and enable wavefront estimation across the coronagraph’s optical planes. The next steps include vacuum testing at the JPL High-Contrast Imaging Testbed (HCIT) for the WFIRST Phase A/B coronagraph demonstration or at Lockheed-Martin’s ATC as part of the EXCEDE Phase A/B.
