Abstract

The optical characteristics of a 5-axis secondary mirror are discussed, stressing the infrared sky chopping and adaptive tip/tilt control capabilities. Sources of image degradation such as misalignments and manufacturing errors are considered. Different modes of operation for active, chopping, and adaptive control are described and examples of the required speed, range, and precision of these modes are presented.
