We introduce a Fourier transform imaging spectropolarimeter composed of a simultaneous polarization modulator and a Fourier transform spectrometer without slit. The spectropolarimeter enables the generation of four sets of fringe patterns with different polarization states of light from an object point. Fourier transform of the fringe patterns provides four equations of Stokes parameters in various wavenumbers. And we can obtain the full-stokes vector from the equations. The most significant advantage of the method is that the four polarized fringe patterns are obtained simultaneously and separated without aliasing. Additionally, the advantages of the Fourier transform spectrometer are maintained, such as high radiative throughput.
我们介绍了一种由同时偏振调制器和无狭缝傅里叶变换光谱仪组成的傅里叶变换成像光谱偏振仪。该光谱偏振仪能够从物点生成四组具有不同偏振态的条纹图案。对条纹图案进行傅里叶变换可以提供在不同波数下的四个斯托克斯参数方程。我们可以从这些方程中获得完整的斯托克斯矢量。该方法的最大优点是能够同时获得且无混叠地分离四组偏振条纹图案。此外，还保持了傅里叶变换光谱仪的优点，例如高辐射通过率。
