Design of lightweight primary mirror and metering structure for spaceborne telescope

摘要

High-resolution telescope from space comprises electro-optical imagery with a ground resolution lying within the range of 1 to 5 meters. Over the last few years, a number of commercial very high-resolution spaceborne telescopes equipped with digital CCD sensors have been launched and are due for launch in the near future. This paper describes a conceptual design trade studies that explores the structural views for the lightweight primary mirror as well as the metering structure in sub-metric class spaceborne telescope.
