中文摘要：

提出了一种基于幅度调制技术和空间调制干涉成像光谱技术的静态成像光谱偏振仪（SISP）。利用由消色差1/4波片、多级相位延迟器和线偏振器组成的光谱偏振调制模块将入射光的斯托克斯分量信息调制到不同的波数上,利用干涉成像光谱仪单次曝光获得经光谱偏振调制的干涉图,不同的斯托克斯分量在干涉图上分离,再采用傅里叶变换从干涉图上解调出入射光的光谱偏振信息。研究结果表明,本文提出的SISP能够通过单次曝光实现一维空间上的完全线偏振光谱测量,通过推扫方式获得另一维空间信息。

英文摘要：

The principle and instrumental structure of static imaging spectropolarimeter which combines the amplitude modulation and spatially modulated imaging Fourier transform spectrometry technology are presented in this paper.A spectral-polarimetric modulator,which consists of achromatic quarter-wave retarder,multiple-order retarder and polarizer,modulated the Stokes componements of the input light into different wavenumbers,a spatially modulated imaging Fourier transform spectrometer after the spectral-polarimetric modulator got the modulated interferogram in snapshot mode,and the spectrum of the Stokes components could be separated and demodulated from the interferogram.The one dimension of spatial information and its full linear spectropolarimetric information could be acquired in one exposure by the imaging spectropolarimeter,and the other spatial information could be acquired in pushbroom mode.
