Paper Abstract

The first astronomical results using a seven segment edge-matched adaptive mirror are presented. The mirror is a prototype for adaptive secondary mirrors, consisting of seven flat hexagonal mirrors, with inductive edge sensors to measure piston errors, and piezoelectric actuators. A Hartmann- Shack wavefront sensor uses the visible light for centroiding information while the IR image is formed on a 58 X 62 InSb array at 2.2 microns. In addition, a number of mathematical models are presented that illustrate how well the system should perform when correcting atmospheric turbulence.
