Experimental demonstration of spectral linear dark field control at NASA's high contrast imaging testbeds
Phillip K. Poon, Axel Potier, Garreth Ruane +6
Due to the low flux of exoEarths, long exposure times are required to spectrally characterize them. During these long exposures, the contrast in the dark hole will degrade as the t…
Random Vibration Testing of Microelectromechanical Deformable Mirrors for Space-based High-Contrast Imaging
Axel Potier, Camilo Mejia Prada, Garreth Ruane +11
Space-based stellar coronagraph instruments aim to directly image exoplanets that are a fraction of an arcsecond separation and ten billion times fainter than their host star. To a…
Experimental analysis of the achromatic performance of a vector vortex coronagraph
Garreth Ruane, Eugene Serabyn, Camilo Mejia Prada +4
The vector vortex coronagraph is an instrument designed for direct detection and spectroscopy of exoplanets over a broad spectral range. Our team is working towards demonstrating c…
