Abstract

In recent work, we numerically and experimentally demonstrated a new approach to high-contrast wavefront control based on the combination of nonlinear optimization with algorithmic differentiation, which we termed Algorithmic Differentiation Wavefront Control (ADWC). ADWC is more computationally efficient than Jacobian-based control algorithms for Deformable Mirror (DM) actuator counts and focal plane sizes relevant to the planned Habitable Worlds Observatory, which potentially opens a path toward on-orbit wavefront sensing and control. Here, we review these results with a view toward their potential impact on NASA’s planned Habitable Worlds Observatory and describe ongoing simulations and experiments, including extensions to adaptive control.
