摘要

本文基于FPGA，研究了一种结合混合技术和快速傅里叶变换(FFT)的宽带、高分辨率、低成本双通道光纤激光热信号解调系统。它用于实时解调双通道激光信号的频差信息。基于光外差检测原理，利用两台中心波长为1550.001~1550.601nm的单频光纤激光器，输出波长间隔为5~30pm的双通道激光信号，进行拍频信号解调系统实验。实验证明，该电路可以实现对0.41~3.45GHz频段拍频信号的实时检测。频率分辨率高达7.6kHz。

Research on FFT Demodulation System of Double Fiber Laser Beat Signal Based on FPGA

In this paper, based on FPGA, a wide-band, high-resolution, low-cost dual-channel fiber laser beat signal demodulation system is studied, which combines mixing technology and Fast Fourier Transform (FFT). It is used to demodulate the frequency difference information of dual-channel laser signal in real time. Based on the principle of optical heterodyne detection, two single-frequency fiber lasers with central wavelengths of 1550.001~1550.601nm output dual-channel laser signals with a wavelength interval of 5~30pm are used to conduct the experiment of beat signal demodulation system. The experiment proves that the circuit can realize realtime detection of beat signal in the frequency band of 0.41~3.45GHz. Frequency resolution up to 7.6kHz.
