✦ Synopsis

Actively controlled optics are revolutionizing the telescope builders' art, by enabling the use of large segmented mirrors, multiple-aperture telescopes, space telescopes, active atmospheric compensation and other innovations. Designing high-performance controllers for these insU'tnnents requires an accurate means of calculating optical performance: a particular method is presented. A detailed example illustrates some of the challenges that arise.
