Paper Abstract

This paper will present the analysis results taken from a well-designed interferometer SCDU. The objective is to deliver picometer performance to meet the allocated astrometric error budget from SIM PlanetQuest mission. It will describe the validation of optical designs and analysis procedures to achieve high accuracy of the tip-tilt and shear alignments. Then it will enumerate environmental factors essential to the SCDU performances. Finally it will report color-independent 3 picometer Narrow Angle (NA) performance and all-in-one 17 picometer NA performance. The all-in-one pico-performance will require spectral calibration modeling to remove delay differential induced by color.
