摘 要:对人眼模型中晶状体的面型和折射率分布进行了研究,基于晶状体的光学特性,利用光学设计软件Zemax接口技术的调入,采用不同连续公式法分别给出了晶状体不同的梯度渐变折射率分布形式;结合晶状体不同的非球面面型,比较分析了晶状体不同面型和不同梯度折射率分布的组合模型对人眼模型重现实测像差的影响;给出了重现我国人眼实测像差误差最小的晶状体模型.结果显示:晶状体的面型越复杂得到人眼模型的像差与真实人眼的测量像差就越接近;当晶状体采用Zernike面,梯度渐变折射率采用分段函数公式形式时,重现实测像差误差最小.
Lens surface type and refractive index distribution of the crystalline lens model in eye optical model was researched. Based on the lens optical pproperties, the effect of different lens combined models on the human eye model to reproduce the measured eye aberrations was analyzed comparatively with Zemax interface technology. The lens combined models included different surface types and different gradient-index distributions by different continuous formulas. The lens model with the minuam reproduce precision was also presented. The results show that the aberrations of the eye model with complex lens suface is close to measured eye aberrations, the lens model with the minuam reproduce precision includs Zernike surface and gradient-index distribution by piecewise function formulas.
