Abstract

The alignment camera for the Keck Observatory uses a modified Shack-Hartmann test to phase the 36 segments of the primary mirror. The camera also has the capability to do direct imaging (and therefore image stacking), and to perform simple image quality measurements on individual segments. In this paper we motivate several of the design considerations for the alignment camera and describe the overall design.
