摘　　要：亮度计成像精度、存储器数据容量和计算机运算能力决定了近场分布式光度计的探测能力。随着成像技术和计算机技术的发展,近场分布式光度计的测量性能有了革命性的提升。介绍了近场分布式光度计的工作原理,归纳了近场分布式光度计相对于远场分布式光度计的优势。综述了国内外近场分布式光度计的研究进展,对比了部分国内外产品的性能指标。针对近场分布式光度计元数据精度不足、扫描重构速度偏慢和溯源装置适应性受限的现状,从部件、软件和系统等方面归纳了相应的解决方案。结合近场分布式光度计的特点和优势,展望了其在照明显示、交通运输、工业视觉和文物保护等领域的应用。The performance of near-field goniophotometer(NFG)was determined by the imaging accuracy of the luminance meter,data capacity of the disk and computing power of the computer.With the development of imaging technology and computer technology,the performance of NFG has been improved dramatically.The theoretical principle of NFG was introduced,and the merits of NFG compared with far-field goniophotometer were summarized.The development status of NFG was reviewed,while some typical NFGs at home and abroad were compared.In view of the current situation of NFG,including insufficient accuracy of metadata,slow scanning reconstruction speed and limited traceability,the possible solutions from the aspects of components,software and systems were presented.Combined with the characteristics and advantages of NFG,its applications in lighting,display,transportation,industrial vision and cultural relic protection were prospected.
