Abstract

There are considerable potential advantages in throughput, polarization and IR emissivity of performing the adaptive correction at the telescope secondary. However, reliability and safety are key issues. This paper explores a sound engineering approach which is rugged, safe and provides a level of redundancy. A 7-actuator demonstrator is described, together with first results from laboratory testing.
