摘要：
可见光通信（visible light communication，VLC）设备是当前的研究热点，但缺乏对其检测的性能指标与相关仪器、标准。该文从一般VLC设备工作机理出发，分析指出VLC设备必须具有发射调制性能、抗杂光性能、接收性能等方面性能评价需求，相应地提出用调制带宽、带内平坦度、直流杂光抵抗比、频闪杂光抵抗比、最小接收照度值、最大接收照度值作为其具体的评价指标体系，并介绍这些指标的定义、物理意义以及检测方法。该评价指标体系具有全面性、实用性，可为VLC设备检测装置研制与标准制定奠定一定的基础。

Abstract: Visible light communication(VLC) equipment is a research hotspot at present, but it lacks of detection indicators and related instruments and standards. Based on the working of general VLC equipment, this paper points out that it must contain performance evaluation requirements such as modulation performance, anti stray light performance and receiving performance. Correspondingly, the modulation bandwidth, in-band flatness, anti DC stray light ratio, anti stroboscopic stray light ratio, minimum and maximum received value of illuminance are proposed as the specific detection indicators system. This paper also introduces the definitions, physical meanings and detection methods of these indicators. The detection indicators system is comprehensive and practical, and lays a certain foundation for the development and standard setting of VLC equipment testing device.
Keywords: visible light communication;detection indicators system;modulation performance;receiving performance;anti stray light performance
