光源光色对人眼视觉功能影响的模拟研究

人眼可见光波长范围在380 nm到780 nm范围内,在此波段内人眼对辐射进行选择性反应。由于外界刺激辐射光谱的组成不同,使得人眼产生不同的颜色感觉即颜色视觉,因此人眼不仅能感受到外界刺激带来的明暗差别,同时能够感受到事物丰富的色彩变化。人眼的明暗感觉对视觉功效起着重要的作用,在各领域研究人眼视觉功效都主要讨论非彩色条件下的明暗刺激问题(光谱响应度),而对于人眼的视觉机制来说,色彩刺激是视觉感受必不可分的部分。在人工光源照明条件下,光色对视觉功效的影响除了与生理机制相关以外,还会涉及到视觉心理、心理物理等领域,目前还缺乏系统的理论研究方法及成果,该文基于人眼视觉机理及光谱响应特性的研究方法,尝试利用计算机模拟视觉功效法研究探讨光源光色对人眼视觉功能的影响。

The Simulated Research on the Effect of Color of Light Source on Human Visional Function

The visible spectrum range is 380 nm to 780 nm,human eyes do selective reaction in this range.So we can obtain diverse of colorful vision because of different spectral distribution.In most field,we do research on the condition of non-color vision,but color is one of the most important factors in the process of vision.In the condition of artificial luminaries,the effect of color of light source on human visional function is not only relate to physiological mechanism but also concern with visional psychology,psychophysical and so on,but there still be lack of relative theory research methods or results.In this paper,we＇ve used computer-simulate method to do research on the effect of color of light source on human visional function based on the mechanism of visional function and the methods of spectral reaction theory.
