A high-throughput polarization interferometer is being developed to demonstrate for the first time the utility of Fourier transform spectroscopy for Thomson scattering diagnostics of high temperature plasma. Target Te and ne ranges for the prototype polarization interferometer are < 1 keV and > 5 × 1018 m-3 , respectively. This paper describes the design of the polarization interferometer and the results of initial tests.
