【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.
[Abstract]:The profile and refractive index distribution of the lens in the human eye model are studied. Based on the optical properties of the lens, an optical design software Zemax interface technology is used. The different gradient refractive index distributions of the lens are obtained by using different continuous formulas, and the different aspherical surfaces of the lens are combined with each other. In this paper, the effects of the combination models of different lens faces and different gradient refractive index distributions on the reconstruction of human eye model are compared and analyzed, and the lens model with the smallest error in the reconstruction of human eye aberration in China is presented. The results show that the more complicated the lens face is, the closer the aberration of the human eye model is to the measurement aberration of the real human eye, and when the lens adopts Zernike surface and the gradient refractive index adopts the piecewise function formula, the error of reproducing the measured aberration is the least.
