本文介绍采用异色视亮度匹配法,用A光源照明,在2°和10°视场条件下测量明视觉光效率函数V(λ)的实验装置、方法及结果。观察者中有汉族、朝鲜族和哈萨克族,测量结果无明显差异。在2°视场条件下对16名观察者测得的V(λ)值与国外9个实验室对37名观察者的平均值相符。
This paper introduces the experimental setup, method and result of measuring the luminous efficiency function of the visible light V (λ) under the condition of 2 ° and 10 ° field of view using the method of color matching of different colors and illuminating with A light source. Observers Han, Korean and Kazakh, no significant difference in measurement results. The V (λ) value of 16 observers at 2 ° field of view was in agreement with the average of 37 observers from 9 laboratories abroad.
