亚利桑那大学开发了一种用于快照成像光谱偏振测量的革命性技术，这是由于最近可获得大型焦平面阵列和研究工作站上更高的计算性能。这项技术涉及成像偏振仪和计算机断层成像光谱仪(CTIS)的结合。这种光谱偏振仪使用调制将所有四个斯托克斯参数的光谱相关性编码到一个光谱中。CTIS是一种快照成像光谱学方法，它使用医学计算机断层成像的逆数学技术重建空间和光谱信息。这些技术的结合为快照成像全斯托克斯光谱偏振仪提供了基础，该仪器可以实现红外光谱的无运动部件。
A revolutionary technique for snapshot imaging spectro-polarimetry has been developed at the University of Arizona due to the recent availability of large focal plane arrays and greater computing performance on research workstations. The technique involves the combination of an imaging polarimeter with computed tomography imaging spectrometer (CTIS). This spectro-polarimeter uses modulation to encode the spectral dependence of all four Stokes parameters into a spectrum. CTIS is a snapshot imaging spectrometry method in which both spatial and spectral information is reconstructed using the inverse mathematical technique of medical computed tomography. The combination of these techniques provides the basis for a snapshot imaging complete Stokes spectro-polarimeter that can be implemented with no moving parts for the infrared spectrum.
