| 摘 要： | 提出一种利用相位载波的调制解调技术实现白光干涉系统复用的周界安防新方法.该系统在单芯反馈式白光干涉系统的若干感应端,分别串接工作在不同频率的相位调制器.首先利用相位调制技术,将不同干涉子系统的感应端的触发信号从频域上分开；再使用相位解调技术,从同一干涉系统输出信号中获得相应于不同感应端的独立时域信号.实验中通过布设在现...

| Abstract: | A novel technology for security system was proposed based on phase carrier modulation-demodulation in this paper,to realize the multiplex of the white light interference system.In several sensing terminals of the single core feedback white light interference system,there are several phase-modulators which worked at different frequencies.The trigger signal in the different interference subsystems could be separated by phase modulation technology.The signals of the different interference subsystems could be d... |
