本报告包含10个光度系统（4个用于2°视野，6个用于10°视野）的最新版本，这些系统已提交给CIE第1部分，作为评估整个人类视觉灵敏度范围内灯光相对亮度的方法。为了对这些系统进行定量测试，每个系统都应用于独立实验室提交的几组数据，这些数据采用了不同的刺激集和异色亮度匹配（HCBM）的不同实验程序。此外，每个系统应用于6个研究组在非常相似的实验条件下使用相同颜色样本进行的HCBM实验中获得的数据。这些数值测试主要是为了观察亮度匹配刺激的等效亮度是否相等，而不是测试亮度缩放的绝对水平。本报告描述了这些定量测试的结果； 它没有推荐新的CIE系统。技术报告共82页，94个图表和9个表格。

This report contains the most recent versions of 10 photometric systems (4 for 2° and 6 for 10° fields) which have been proposed to CIE Division 1 as methods of assessing the relative brightness of lights across the entire range of human visual sensitivity. To provide quantitative tests of these systems, each system has been applied to several sets of data submitted by independent laboratories employing different stimulus sets and different experimental procedures for heterochromatic brightness matching (HCBM). Furthermore, each system was applied to data obtained in HCBM experiments performed by 6 research groups using the same coloured samples under very similar experimental conditions. These numerical tests were primarily intended to see the equality of equivalent luminances for brightness-matched stimuli but not to test the absolute level of scaling for brightness. This report describes the results of these quantitative tests; it makes no recommendation for a new CIE system.The Technical Report consists of 82 pages with 94 figures and 9 tables.
