Intensity modulation-Fourier transform spectropolarimetry (IMFTSP) is a novel technology that combines the intensity modulation spectropolarimetry and Fourier transform spectroscopy. The IMFTSP can obtain full Stokes spectropolarimetric parameters simultaneously, and maintains the throughput (Jacquinot) and multiplex (Fellgett) advantages. Yet aside from this, the IMFTSP has the advantage of reducing the complexity of data processing. The data collecting and spectropolarimetric parameters reconstruction processes were analyzed theoretically in this paper, the theoretical formulas are presented, and a whole process mathematical simulation for the IMFTSP system is introduced. The theory analysis and simulation results proved the feasibility of the IMFTSP.%强度调制-傅里叶变换光谱偏振技术是一种综合强度调制光谱偏振技术和傅里叶变换光谱技术的新型光谱偏振测量技术,能够同时实现全斯托克斯光谱偏振参数测量,保留了傅里叶变换光谱技术高通量、多通道的特点,同时具有降低数据处理复杂程度的优点.文章对强度调制-傅里叶变换光谱偏振测量技术的数据采集和光谱偏振复原过程进行了理论分析,给出了推导公式,并进行了基于该技术的光谱偏振仪工作全过程的数值模拟,理论分析及模拟结果证明了该技术在理论上的可行性.
