摘要:
基于Savart板的新型时空混合调制型偏振干涉成像光谱仪（TSMPIIS）是一种静态、小型化、高稳定性的遥感偏振探测器件,可以用来实现对目标的光谱信息以及偏振信息的探测.目前,已经确立了通过旋转TSMPIIS偏振片法来实现测量的方案,然而该方案破坏了TSMPIIS系统原有的稳定结构,降低了仪器的测量精度和可靠性.为克服旋转偏振片法的不足,本文从TSMPIIS的探测原理出发,通过分析和计算TSMPIIS的Mueller矩阵,推导出了全视场角度的TSMPIIS旋转偏振探测法的基本公式,论证了TSMPIIS全视场偏振信息探测的可行性和准确性,为TSMPIIS的遥感探测以及Stokes参数的反演提供了理论依据,进一步拓展了TSMPIIS遥感探测的优越性.
Abstract:
Spatiotemporally modulated polarization interference imaging spectrometer（TSMPIIS）is static,miniature,stable instrument for remote sensing polarization detecting,which can be used to obtain the spectral and the polarized information about the target.It has been approved that TSMPIIS can obtain the target information by circumrotating its polarizer.However this method destroys the structure of TSMPIIS and reduces the measurement accuracy.According to the detecting theory of TSMPIIS,in this paper,we derive the basic equations for TSMPIIS detecting by analyzing and calculating its Mueller matrix,and authenticate the feasibility and the veracity of TSMPIIS for polarization detecting in full field of view.This work is very helpful for TSMPIIS remote sensing detecting and the retrieval of Stokes parameters.
