Optical design of a compact telescope for the next generation Earth observation system
Author(s): Vincent Costes; Guillaume Cassar; Laurent Escarrat

Paper Abstract

High resolution earth observing systems need bigger and bigger telescopes. The design of such telescopes is a key element for the satellite design. In order to improve the imaging resolution with minimum impact on the satellite, a big step must be made to improve the compactness of the telescope.

This paper describes the comparative study of several compact optical designs. This compactness increases drastically the sensitivity of the telescope. The optical designs, their sensitivity, their performances, the need to implement active optics are discussed.
