摘　　要：该文介绍了自行研制的、根据视觉功效法进行中间视觉研究的反应时间测试系统。该系统与实际的视觉作业环境相结合，采用不同光源形成中间视觉下的光照环境，用变化的目标光斑模拟夜间道路中可能出现的障碍物，并通过电子快门记录受测人员确认光斑的反应时间，由此求得等效亮度时的光源相对光效和评价人眼真实的视见能力。该文对系统的构造、工作原理、实验及数据处理方法、应用结果等进行了分析和讨论。事实证明，该系统为创建中间视觉光度学模型提供了有效的实验条件，并对我国道路和隧道照明工程的实施具有重要的应用价值。The paper introduces a self- developed reaction time test system, based on the law of visual effects for the intermediate visual study, By combining the system with the visual environment of actual operation, adopting different light formed illumination environment under the intermediate visual, using variational goal photic fleck, and simulating possible obstructions on the night road and affirmed photic fleck of reaction time by the electronic shutter recorded, the source relative efficiency under the equivalent brightness light can be obtained, and the visual ability of the real eye can be evaluated, This paper analyzes and discusses the structure of the system, working principle, experi- mental methods and data processing, application of the results, and so on. Facts proved that the system for the creation of intermediate visual luminosity model provides an effective experimental conditions and important value for road and tunnel lighting project.
