Paper Abstract

A lightweight segmented adaptive optical telescope for spaceborne applications is described and details of a hardware demonstration program presented. This program demonstrates, at a 4-meter aperture, a configuration and technologies for large deployable imaging systems. Real-time sensing and control is achieved using a suite of sensors to continuously measure wavefront error and segment phasing. The resulting state vector is operated on by the control algorithms and the resultant optimization commands applied to precision actuators to correct the system wavefront. The demonstrated technologies are discussed, along with details of the space qualifiable hardware configuration. These technologies include: a shearing interferometer wavefront sensor, autonomous hierarchical control sequences, lightweight graphite composite structures, and large lightweight optics.
