摘要
在光轴和视轴不重合的眼球模型中,设计了一种仅消轴向色差(LCA)而保持横向色差(TCA)不变的元件,建立了仅有TCA的眼模型。进而将实测的人眼高阶像差数据沿视轴方向引入眼模型,用以研究色差和高阶像差的相互作用。建立了三款个性化眼球模型,研究了明视觉状态下高阶像差、色差(LCA+TCA)、LCA和TCA对视觉的影响以及它们之间的相互作用。结果表明:对于多数人眼,色差对视觉的影响远大于高阶像差的影响,并且色差的存在进一步抑制了高阶像差的影响。在色差对视觉的影响中,LCA是具有统治地位的因素;对于多数人眼,TCA的影响可以忽略。
In the eye model involving the angle formed by visual and optical axis, an achromatic element eliminating longitudinal chromatic aberration （LCA） only while maintaining transverse chromatic aberration （TCA） is designed and the eye model of TCA-only is constructed. Furthermore, the actual data of human eye＇s higher-order aberrations are introduced into the eye model along visual axis to investigate the interaction between chromatic and higher-order aberrations. Three kinds of individual eye models are constructed to investigate the impact of higher-order aberrations, chromatic aberration （LCA＋TCA）, LCA and TCA on vision under the photopic condition, as well as their interactions. The results show that for most of the eyes the impact of chromatic aberration on vision is far greater than that of higher-order aberrations and the presence of chromatic aberration further reduces the impact of higher-order aberrations. Among the impact of chromatic aberration on vision, LCA is a dominant factor, and the impact of TCA can be ignored for most of the eves.
