| 中文摘要: |
| 研究了菲涅耳透镜成像质量差的原因,提出一种改进的方法,即改善轴外点的成像质量以增大菲涅耳透镜的视场.分析了三种常用的设计菲涅耳透镜的方法,用光学设计软件Zemax模拟设计结果,对三种设计方法进行比较.得出结论:像面为曲面时可校正场曲;基面和底面为曲面的菲涅耳透镜与平面型菲涅尔透镜相比彗差较小. |
| 英文摘要: |
| The flaw of Fresnel lens was analyzed, and a method was brought up to broaden the angle of Fresnel lens and to improve imaging quality.Three methods of Fresnel lens design were listed,and there type of lens were simulated,and the results of simulations were compared,and the conclusion is: curve detector can lighten field curvature.The imaging quality of curve Fresnel lens is better than plane one,because coma aberration was corrected. |
