Abstract

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.
