摘要
麦克斯韦鱼眼球形透镜对近距物点以最小像差成像时,往往要求较大的折射率差值△n ̄[1],目前的离子交换制作工艺尚难达此技术水平。为解决此困难,本文提出将此类球透镜置于低折射率均匀介质内组成复合结构,可在保持最小像差的提前下,大幅度减小其对折射率的差值△n的要求。
When,Maxwell fisheye sphere lens images for the short distance object point with small-est aberration,the bigger difference of refractive index △n is required,but the present ion-exchange technology is hard to reach this level.in order to resolve this problem,a compound structure formed by the kind of sphere lens placed in smaller index homogeneous mediums is proposed so as to reduce the re-quirement for the difference of refractive index greatly on the premise of keeping smallest aberration.
