Abstract

Larger mirrors, even than the primary mirror of the JWST, is a necessity for the UV-Vis design to go further. Our NASA Innovative Advanced Concepts (NIAC) funded project is called A Precise Extremely large Reflective Telescope Using Reconfigurable Elements (APERTURE). The project is based on the idea of deploying a large, continuous, flexible membrane mirror and correcting the mirror shape after deployment to within λ/20 deviations. The main contribution of this study is executing the corrections using a contiguous coating of a Magnetic Smart Material (MSM) instead of using classical piezoelectric-patch or electrostatic actuation technology. The corrections are applied by a magnetic write head which will move on the non-reflective side of the membrane mirror. In this paper, selection and design process of the deployment mechanism, and the design of the experimental setup for surface measurements is discussed. The design process of the deployment mechanism for the flexible membrane mirror is presented, lessons learned from it, and future work that needs to be done.
