摘要:
利用重采样频域滤波(resample frequency domain filter,RFDF)方法,提取高荧光及随机噪声背景下的拉曼信号.仿真结果表明,在设计适当的滤波器情况下,该方法能得到很好的拉曼信号提取效果.若要获得较高的拉曼光谱信号保真度,需考虑不同成分信号功率谱的混叠程度、光谱数据的分辨率和采样率、频域带通滤波器的设计形式及参数等影响因素.
Abstract:
Resample frequency domain filter (RFDF) was used to extract Raman spectra from high fluorescence and random noise. The results of simulation confirmed that the weak signal of Raman spectra could be extracted from the background. In order to obtain better fidelity of Raman spectra,several factors should be considered, including the aliasing of different components of power spectra, the resolution and sampling rate of spectra data and the band-pass filter.
