Variable period characteristics of light propagation in a conical GRIN rod-geometrical optics analysis
In this paper based on the ray path equations, the variable period characteristics of light propagation in a conical GEIN rod are analyzed. The analytical expressiona for the period of rod are obtained and used to calculate the periods of some conical GRIN rods. The quater pitch rods and the corresponding focal lengths are also given for GRIN rod lenses design.
