We have carried out both theoretical and experimental studies of the sensitivity of dark hole contrast to the control bandwidth and dark-hole dimensions in high-contrast broadband stellar coronagraphy.
High-contrast coronagraph performance in the presence of DM actuator defects
Aug 9, 2015
Sidick, Erkin; Shaklan, Stuart; Cady, Eric, 2015, "High-contrast coronagraph performance in the presence of DM actuator defects", https://hdl.handle.net/2014/45746, SPIE Optics + Photonics, San Diego, California, August 9-13, 2015, JPL Open Repository
We have carried out experiments on our High-Contract Imaging Testbed (HCIT) to study the impact of failed actuators in partial fulfillment of the Terrestrial Planet Finder Coronagraph optical model validation milestone. We show that the wavefront control algorithm adapts to sever...

Studies of the effects of optical system errors on the HCIT Contrast performance
Aug 21, 2011
Sidick, Erkin; Shaklan, Stuart; Give'on, Amir; Kern, Brian, 2011, "Studies of the effects of optical system errors on the HCIT Contrast performance", https://hdl.handle.net/2014/43789, Proceedings of SPIE 8151, Techniques and Instrumentation for Detection of Exoplanets V, 815106 (15 September 2011), SPIE Optics + Photonics 2011, San Diego, California, August 20-25, 2011., JPL Open Repository
The High Contrast Imaging Testbed (HCIT) at the Jet Propulsion Laboratory employs a broadband wavefront correction algorithm called Electric Field Conjugation (EFC) to obtain the required 10-10 contrast. This algorithm works with one deformable mirror (DM) to estimate the electri...
