【Abstract】 A typical ray path equation in a paraboloidal GRIN rod lens is derivedfrom the variational method. It is shown that the ray paths depend strongly on thespot size and the inclination of the incident beam and rod parameters. The geome-trical optics result is the reduced result of this paper.更多还原
