Abstract

In ‘Active Optics II’, the active correction of a 1 m test mirror was described in detail. A residual aberration term was found which still required correction in order to achieve the aim of the experiment: removal of all systematic defects leaving only statistical or high-frequency noise. The present paper describes the interferometric confirmation of the term and this final correction stage of the 1 m experiment.
