Paper Abstract

In context of wavefront control for high-contrast coronagraphy, we present the spectral characterization of speckles generated by deformable mirrors (DMs) at various distances downstream of the pupil plane. We have measured the focal-plane electric field at 600 to 690nm of speckles generated with an in- and out-of-pupil DM on a highcontrast testbed using a self-coherent camera. These measurements are analyzed analytically and are compared to numerical end-to-end simulations of the setup. This will aid in the design of wavefront correction algorithms with multiple DMs.
