论文摘要
一个中心系统在另一个球形盖上形成了球形盖上光场的连贯图像，其顶点和曲率中心是对象盖的顶点和中心的各自的近距离图像。 ``通常在标量衍射理论的框架中获得的``双重轭''定律是从几何光学概念中得出的。共轭球形胶囊半径之间的放大率将纵向放大倍率的概念扩展到有限的距离，并概括了纵向Lagrange-Helmholtz公式。将双缀合法应用于成像高斯梁，表明这些光束完全遵守几何光学法则。
A centred system forms the coherent image of the optical field on a spherical cap, taken as an object, on another spherical cap, whose vertex and curvature center are the respective paraxial images of the vertex and center of the object cap. That ``double-conjugation'' law, usually obtained in the framework of a scalar theory of diffraction, is deduced from concepts of geometrical optics. A magnification law between radii of conjugate spherical-caps extends the notion of longitudinal magnification to finite distances, and generalizes the longitudinal Lagrange-Helmholtz formula. Applying the double-conjugation law to imaging Gaussian beams shows that those beams perfectly obey geometrical optics laws.
