摘要
散射是入射光线由于人眼内屈光介质折射率及透明程度不同，而使部分到达视网膜的光线未能参与到视网膜成像的现象。散射降低了视网膜的对比度，从而影响人眼视网膜的成像质量，是影响视觉质量的重要因素之一。近年来，对于人眼散射的研究越来越受到关注。本文将追溯散射理论的发展历史，阐述散射的概念及分类，并对散射光的测量及散射与视觉质量的关系进行综述。
As an influencing factor of visual quality, straylight is a functional measure of the effect of light scatter across the retina. The phenomenon depends on the refractive index and the turbidity of the ocular media. This light scattering reduces the contrast of the image projected on the retina, and thus decreases the quality of vision. The review focuses on the concept and classification of straylight, and the relationship between straylight and visual quality.
