介绍了几种利用空间载波的光谱偏振仪的实现方法。第一种实现方式包括两个Savart板和包括二维CCD的光谱仪，以产生具有空间载波的光谱。在每个波长处沿空间坐标沿着进行频率滤波，使我们能够进行波长分辨斯托克斯参数的快照测量。SOP测量的光谱分辨率可以提高到光谱仪的分辨率。在第二种实现中，使用了两个消色差双折射棱镜对来减少光谱偏振计设计中的限制。最后，将该方法与通道化光谱偏振态发生器相结合，通过对二维光谱的快照测量，确定样品的光谱Mueller矩阵。
Several implementations of spectroscopic polarimeters using spatial carriers are presented. The first implementation incorporates two Savart plates and a spectrometer including a two-dimensional CCD to generate a spectrum with spatial carriers. The frequency filtering along the spatial coordinate at each wavelength allows us to conduct the snapshot measurement of the wavelength-resolved Stokes parameters. The spectral resolution of the SOP measurement can be enhanced up to that of the spectrometer. In the second implementation, two achromatic birefringent prism pairs are used to decrease the limitation in the design of the spectroscopic polarimeter. Finally, the present method is combined with a channeled spectroscopic polarization state generator so that the spectroscopic Mueller matrix of a sample can be determined by the snapshot measurement of the two-dimensional spectrum.
