Description

Focalisation de rayons parallèles par une miroir parabolique. La figure de gauche montre que la focalisation est imparfaite, les rayons non parallèles à l'axe ne se coupent pas tous au même point. La figure de droite montre de manière caricaturale la focalisation approché dans les hypothèses de Gauss.
