| 摘 要： | 采用直接亮度法针对逆反射亮度系数测量展开研究。搭建了测试系统,以逆反射标志为测试对象进行了实验测试,并将直接亮度法与直接发光强度法进行了对比。实验结果表明,直接亮度法在暗室杂散光要求、测试对象、测试距离以及结果的准确度等方面均比直接发光强度法有明显优势,而且测试过程简单,结果不确定度为3.27%(k=1.96)。 |
| 关 键 词： | 计量学 逆反射亮度系数 直接亮度法 不确定度 |

| Abstract: | The direct luminance method is used to measure the coefficient of retroreflected luminance.The test system is build and the experiment is carried out with the retroreflected marks as the test object.The test and comparison of the direct luminance method and direct luminous intensity method is conducted.The experiment results show that the direct luminance method has obvious advantages on the aspects of the stray light requirement of the darkroom,the measurement object,the measurement distance,and the measurement accuracy.At the same time the direct luminance method has the advantages that the measurement process is simple and the measurement uncertainty reach 3.27％ (k =1.96). |
| Keywords: | metrology coefficient of retroreflected luminance direct luminance method uncertainty |
