眼倍率色差的实验测定与理论分析

Theoretical Prediction and Expermental Determination of the Chromatic Difference of Magnification of the Eye

提供一种计算人眼倍率色差的简化模型。理论分析得：倍率色差与轴向色差，以及人射光瞳至节．点问轴向距离成正比。眼睛观察前五平行平面视觉倾斜对视网膜成像大小非常敏感，利用这种技术，通过一个辅助连镜可以测量人眼双眼倍率色差的平均值，从而得到单眼的倍丰色差．对实验结果作分析，可得与理论模型相一致的关系。

This paper provides a simp1e model for calculating the chromatic difference ofmagnification(CDM)for the human eye. Spectral differences in image size are proportion tothe eye's longitudinal chromatic aberration and the axial distance between the entrance pupiland nodal point. Reliable tilts in the AFPP can be detected with small interocular differencesof magnification. A method exploits this great sensitivity and measures the average monocu-lar CDM value of the both eyes with an afocal lens,so CDM of a single eye is detemined. Theexperimental results are consistent with the theoretical model'
