A Phasing testbed for the Giant Magellan Telescope

Abstract

In this paper we propose a conceptual design for a testbed to be constructed for the purpose of solving several of the challenges that GMT will face to phase its segmented mirrors. With the proper design, this testbed can be used, not only to test all the phasing controls and algorithms, but also its wavefront sensors and instruments. The testbed will therefore play an important role during commissioning of the observatory with a big impact on its productivity. We present the conceptual design of the phasing testbed and its key requirements. Show more
