基于相移光栅的多频点瞬时频率测量
|
摘要
文章提出了一种新型的基于相位调制器和相移光栅来实现多频点瞬时频率测量的方法,它是基于相位调制到强度调制的转换。当多频点信号经过相位调制器调制后输入到相移光栅时,调谐光源的波长随时间变化,经过光电探测后得到光源波长与输入频率的映射关系,同时得到扫描时间与输入频率的映射关系,最终分析出该信号的各个频率。经过仿真实验证明,它可以对50MHz~20GHz宽带微波信号进行多频点、分辨率为50MHz的测量。
A novel multiple frequency measurement based on phase modulator and phase shift fiber Bragg grating was proposed and stimulated in this paper.It was realized by phase modulated to intensity modulated.When the multiple frequency signal modulated by phase modulator falls into the phase shift fiber Bragg grating,tuning the laser wavelength with time,the mapping relationship between the laser wavelength and the input frequency is got by the photonic detector.At the same time,the mapping relationship between the scanning time and the input frequency was obtained.Finally,the multiple frequency of the input signal was got by analysis.The stimulation and experiment demonstrate that the multiple frequencies from 50 MHz to 20 GHz can be precisely measured and the frequency resolution can reach 50 MHz.
