摘　　要：人们一直关注视觉阈值测量与诊断的研究,近年来人眼及其他视觉传感器的色差阈值测量与研究开始引人关注。讨论了一种基于由两路颜色积分球均匀光源共轭产生的可精密调控颜色及其色差目标的装置。该装置基于麦克亚当椭圆理论,选择CIE LUV均匀颜色空间及其色差公式来表示颜色并计算色差ΔE的大小,可实现在较大色域范围内不同颜色中心在不同方向上的颜色宽容量和色差阈值的测量,可为被试者提供色视觉功能的诊断。The color is a common phenomenon in our society and life, and the existence of colors leads to color difference. Almost all walks of life have studied color difference, such as textile, printing, ceramics, building, digital display, image processing and so on. But so far, the study directly of threshold color difference of human eyes is very few. If wanting to research the color difference, firstly to produce colors which resulting in the color difference are needed. Recent studies have found that the sensitivity of human eyes distinguishing colors is more sensitive when using self-luminous color than using reflective color. An apparatus which can generate kinds of colors is designed by adjusting the color-mix machine which is placed between a small integrating sphere and a big integrating sphere. This can provide a precondition for measuring threshold color difference.
