摘　　要：中间视觉光度学一直为国际照明界所关注,CIE191∶2010推荐了基于视觉功能的中间视觉光度学系统。本文论述了USP模型、MOVE模型、MES1模型和MES2模型的研究背景、实验条件以及各自的特点和适用范围。通过对不同S/P值光源的理论分析和实际测量,发现在中间视觉的低亮度区域USP模型精度最高,在高亮度区域MES2模型精度最高,因此应根据具体的视觉任务选择合适的模型以达到最高的测量精度,对于采用迭代方法计算光度量的中间视觉模型,还应保证亮度适应系数不能为负。此外,在中间视觉区域,能量主要集中在短波段的光源比能量主要集中在长波段的光源具有更高的发光效能,如果采用明视觉模型评价中间视觉照明质量,将导致错误的结果。The mesopic photometry has been a topic of concern in the international lighting community, and mesopic photometry system based on visual performance is recommended in CIE 191：2010 technical report. In this paper, the background, experimental conditions, characteristics and applicability of USP, MOVE, MES1 and MES2 system are discussed. By theoretical analysis and measurement of light sources with different S/P, it was found that the USP system possesses the highest accuracy in lower luminance of mesopic region, while MES2 system the highest accuracy in higher luminance, so appropriate system should be selected according to specific visual task. When mesopic luminance is determined iteratively, the adaptation coefficient may be negative and should be set to 0. In addition, lamps with a relatively high output in the short wavelength region result in higher luminous efficacy in the mesopic region as compared with lamps with relatively high output in the long wavelength, so evaluating mesopic lighting with photopic system will lead to incorrect results.
