摘要：

介绍了一种测量Stokes矢量元素谱的新方法。该方法通过在普通光谱仪的入射光路前端加上由两个延迟器和一个检偏器组成的调制器，只需一次测量即可解调得到目标的完整Stokes矢量元素谱，能有效解决传统偏振光谱信息获取方法存在的缺陷。给出了新方法实现完整Stokes矢量元素谱测量原理的数学推导，并用计算机数值模拟手段证明了该方法的可行性。

Abstract:

A novel method measuring the Stokes elements spectral was proposed. The main idea of the method is that a modulator consisted by two retards and one polarizer was placed before the spectrometer and let the light under test go through the modulator to the spectrometer. Measuring the power spectral from the modulator only one time and executing the demodulation algorithm, the whole Stokes elements spectral from the light under test could be obtained. The disadvantages of the old methods could be removed completely by the new method. The principle measuring the Stokes elements spectral based on the new method is deduced in detail and its feasibility is proved by the numerical simulation.

Key words: remote sensing, polarization, Stokes elements spectral, intensity modulation, numerical simulation
