A Telescope for Imaging the Sun on Board CubeSat Small Spacecraft

摘要

A small space telescope intended for imaging the Sun on board CubeSat small spacecraft has been developed and produced in the form of a ground-based model. A compact two-mirror optical system has been proposed for the telescope and tested. Using it, high-quality images of the Sun can be obtained with an angular resolution of better than 4 '' in the EUV spectral region of the solar spectrum, where the main radiation of active solar processes lies. The expected quality was simulated for images that cannot be experimentally obtained and investigated under the ground conditions. The ability of the telescope to record all principal phenomena of the solar activity (flares and eruptive prominences) has been confirmed.
