本文从光线轨迹方程出发,讨论锥形发散梯度折射率纤维透镜成象的光学特性;导出大端,小端对目标成象的最大孔径和视场的表达式,以及大端孔径视场与小端孔径视场之间的相互关系。
In this paper, the optical characteristics of conical divergent gradient refractive index fiber lens are discussed based on the ray trajectory equation. The maximum aperture and the field of view of the target imaging at the large end and the small end are deduced. The relationship between the end aperture field of view.
