We analyze the work on geometrical optics by Felice Casorati who contributed to the dissemination of Gaussian optics in Italy. In his approach to Gauss's (1840) Untersuchungen he applied determinants to describe multiple refractions in an optical system and he explored the extension of the theory to cover slightly non-centered optical systems for which he introduced the cardinal line, a straight line that replaces the optical axis in this framework.

Felice Casorati 和意大利对高斯光学的接受

我们分析了 Felice Casorati 在几何光学方面的工作，他为意大利的高斯光学传播做出了贡献。在他对 Gauss (1840) Untersuchungen的方法中，他应用行列式来描述光学系统中的多重折射，并探索了将该理论的扩展以涵盖略微非中心的光学系统，为此他引入了基数线，一条直线取代了此框架中的光轴。
