Microelectromechanical deformable mirror development for high-contrast imaging, part 1: miniaturized, flight-capable control electronics

Deformable mirrors (DMs) are a critical technology to enable coronagraphic direct imaging of exoplanets with current and planned ground - and space-based telescopes as well as future mission concepts that aim to image exoplanet types ranging from gas giants to Earth analogs. This places several requ...

Zusammenfassung:	Deformable mirrors (DMs) are a critical technology to enable coronagraphic direct imaging of exoplanets with current and planned ground - and space-based telescopes as well as future mission concepts that aim to image exoplanet types ranging from gas giants to Earth analogs. This places several requirements on the DMs such as requires a large actuator count (>3000), fine surface height resolution (
