摘　　要：通过文献分析,溯源小目标可见度概念的形成过程,探讨小目标可见度与阈限亮度差之间的对应关系,并建立公路隧道光环境下对比显示系数与阈限亮度差之间的关系,分析观察者年龄、小目标物正负亮度对比和小目标物呈现时间对阈限亮度差的影响作用,为系统研究对比显示系数和察觉对比法提供参考。According to literature analysis method,this article traced the formation process of the concept of small target visibility.It is important to determine the correspondence between small target visibility and minimum luminance threshold.The relationship between contrast revealing coefficient and minimum luminance threshold can be established in road tunnel light environment.Then,the correction coefficients which corrected the minimum luminance threshold included the age correction coefficient,the correction coefficient of small target exposure time and the correction coefficient of positive and negative luminance contrast.This review can be used as a basis for subsequent systematic research on contrast revealing coefficient and the perceived contrast method.
