PURPOSE
To derive general equations that characterize rays, magnification, and blur at the retina in the case of near object points for the naked eye and for the eye in combination with a general optical instrument.
METHOD
The paper draws on results obtained via linear optics in an accompanying paper.
RESULTS
Equations are presented that completely characterize the state of rays at the retina from objects at any distance. They allow quantification of blur, size, shape, orientation, and magnification at the retina.
CONCLUSION
The analysis provides a framework, complete in linear optics, for the analysis of light arriving at the retina of a general eye through any instrument from any object point.
目的
推导通用方程，用于描述裸眼以及与通用光学仪器组合的眼睛在近物点情况下视网膜上的光线、放大率和模糊情况。
方法
本文借鉴了随附论文中通过线性光学获得的结果。
结果
给出了方程，这些方程完全描述了来自任意距离物体的光线在视网膜上的状态。它们能够对视网膜上的模糊、大小、形状、方向和放大率进行量化。
结论
该分析提供了一个在线性光学中完整的框架，用于分析从任意物点通过任何仪器到达普通眼睛视网膜的光线。
