Abstract

The purposes of the Phase II alignment are to coalign mirror pairs for the FOC and FOS channels and to set the compensation mechanisms of each channel to the optimum positions to allow the overall system performance to be determined and verified through use of the RAS/HOMS equipment without requiring adjustment of the mechanism compensators during testing. This alignment process is performed with the COSTAR instrument installed in the COSTAR Alignment System (CAS), using a well characterized interferometer system as the optical source. The interferometer uses a custom designed reference sphere with built-in spherical aberration to enable the highly aberrated two-mirror systems to be observed in double-pass.
