An original classification of obscuration-free telescopes designs unfolded in two dimensions
Benjamin Aymard, Andrea Delahaye, Audric Drogoul
In this article we propose an original classification method for unobscured imaging systems unfolded in two dimensions. This classification is based on a study of off-axis properti…
