摘要
以紫外气体放电灯为通信光源,在深入研究气体放电灯的特性和电子镇流器工作原理的基础上,采用延时电感控制技术,设计了一款基于BFSK的紫外光调制电路,对调制电路进行了实现与测试。通过实验观察和测试表明,所设计的调制电路所产生的BFSK信号频谱符合低速数据通信要求。
On the basis of the performance of gas discharge lamp and the principle of electronic ballast, adopted technique of dynamic inductance control, an ultraviolet modulation circuit based on electronic ballast is designed and realized. Then the BFSK modulation experiment using low pressure mercury lamp is performed. The results show that the spectrum of BFSK signal created by modulation circuit meets the request of a low rate data communication.
