摘　　要：以紫外荧光灯为光源,结合调频和鉴频技术可实现低速率下的紫外通信。紫外荧光灯的反应时间偏长已成为了限制通信速率的固有缺点,文章分析了限制紫外通信速率的原因,并针对这些限制因素提出了系列行之有效的解决方法,有效地提高了系统的通信速率。最后指出,大力发展紫外光源将是解决通信速率问题的最终努力方向。Using ultraviolet fluorescent lamp as the light source, combining frequency modulation and demodulation technology can achieve a UV communication system with low date rates. The response time of UV fluorescent light have been an inherent shortcoming of communication rate. This paper analyzes the limiting factor of UV fluorescent, and presents a series of new method to improve the communication rate. This paper also indicates that using UV LED array as the light source will be the ultimate solution to this problem direction.
