Abstract

A laboratory testbed to demonstrate and characterize control systems needed for interferometric nulling has been under development for two years at Ball Aerospace. Our testbed uses visible light and ambient temperature operation in air, unlike the mid-IR, cryogenic vacuum operation that will be used for Terrestrial Planet Finder. We have developed automated, closed-loop control in delay and tip-tilt.
