Abstract

A series of optical systems is considered for the Synchronous Earth Observatory Satellite (SEOS) and classified by field coverage. As field angle increases, so does utility, but the penalty is increased complexity, size, and weight. All-reflective optical configurations are required by the wide spectral range requiremnt and the 1.5-meter diameter equivalent area aperture size. A series of telescope designs has been developed to confirm design viability, to eliminate physical/ mechanical interference, and to generate preliminary envelope and packaging data. The optical designs were carried to the modulation transfer function (MTF) level. The range of field angles investigated varied from a few arc-minutes square to more than 7 degrees x 3 degrees. The configurations and comparisons of utility, performance, size, and weight are discussed, and impacts on the mission and subsystems are considered.
