Paper Abstract

A technique developed at ESTEC for the measurement and theoretical estimation of optical polarization in the antenna telescopes of space optical communication systems (e.g., the ESA SILEX intersatellite system using 825-nm semiconductor lasers) is described. The design methods used to achieve high channel separation ratios in the SILEX telescopes are recalled; the failure of straightforward measurement techniques in practical ground-based testing is explained; and a solution based on the mathematical relationship between far-field and near-field intensity distributions is outlined. The primary instrument used in this method is a scanning ellipsometer.
