After first developments at CEA-Leti on curved sensors and the demonstration of highly compact optical systems benefiting from curvature, this thesis explores the use of curved microdisplays in visuals systems to make them more compact. Advantages of

International audience; In this Letter, we present a method to design the freeform surfaces of an off-axis unobscured two-mirror telescope by integration of a system of differential equations. The system is derived from the differentiation of Fermat

International audience; We present a method where an ordinary differential equation problem is derived from the Fermat path’s principle and is integrated to construct freeform surfaces. We discuss preliminary results of the method, its limitations

Le besoin en haute performance en termes de qualité image, résolution et champ de vue accroît la complexité et le budget masse/volume des instruments optiques. Ces contraintes impactent toutes les applications: l’astronomie, la défense, les mi
