| 摘 要： | 针对单强度调制偏振光谱测量技术存在混叠且有效光程差有限的缺点，提出双强度调制偏振光谱测量新方法，该方法通过双强度调制干涉信号的和差处理，即保证单强度调制偏振光谱测量的优点，又能有效消除混叠现象，提高有效光程差和光谱分辨率，再对和差处理后的干涉信号进行傅里叶变换即可得到被测偏振光谱。文章对双强度调制偏振光谱测量方法进行了理论推导，并通过MATLAB对模拟入射光偏振光谱的干涉信号和傅里叶反演光谱进行仿真；仿真结果显示，该方法和差处理后可有效消除混叠且有效光程差提高一倍。通过理论分析和仿真验证了该方法的可行性，为进一步的工程实现提供理论支撑。

| Abstract: | Due to single intensity modulated polarization spectrum measurement technology has aliasing phenomenon and effective optical path difference is limited, double intensity modulated polarization spectrum measurement was presented. This method not only has the advantage of a single intensity modulation spectropolarimetry, but also effectively eliminates the aliasing phenomenon and improves the effective optical path difference and the spectral resolution by sum-difference processing of the double intensity modulation interference signal. The sum-difference signal Fourier transform was used to get the polarization spectrum. The interference signal of incident spectrum and Fourier inversion spectrum were simulated by MATLAB. Simulation results show that this method effectively eliminates aliasing and gets double effective optical path difference after the sum-difference treatment. The principle for measuring the spectrum of the Stokes components based on the double intensity modulation spectropolarimetry is deduced in detail and its feasibility is proved by the simulation, which provides the necessary theoretical basis for engineering implementation of this method. |
