摘　　要：为了实时获取静态迈克尔逊干涉仪得到的光谱信息,设计了基于FPGA的实时光谱采集分析系统。在Xilinx FPGA芯片上实现了干涉条纹到光谱数据的实时处理。在算法处理过程中,实现了干涉条纹滤波去噪、快速傅里叶变换、相位标定、光谱数据传输等模块化功能。实验结果显示,系统可以高速采集并实时处理光谱数据。For real-time access to the spectrum information of static Michelson interferometer, designed real-time spectrum ac- quisition and analysis system based on FPGA. The system achieved real-time processing of the spectrum data from interference pat- tern by hardware language Verilog HDL on the chip of Xilinx FPGA. In the algorithm process, the system achieved the interference fringes denoising filter, fast Fourier transform, phase calibration, spectral data such as modular functions. The results show that the system can handle high-speed acquisition and real-time spectral data.
