Abstract

A 4-channel Fourier transform polarization spectrometer is conceptually proposed and experimentally demonstrated as an extension of the conventional Fourier transform spectrometer for scalar spectra collection. The design consists of a typical Michelson interferometer and four sets of polarizer arrays inserted into the incident light path, two interference arms and an output light path, respectively. This novel device facilitates the measurement of all elements in the coherence tensor of a radiative source simultaneously. As an extension of the Wiener-Khintchine theorem, the four sets of spectra with polarization information can be recovered by applying Fourier transforms to the recorded sets of interferograms. The reconstructed polarization spectra have been displayed on a Poincare sphere to demonstrate how a light source emits radiation at each wavelength with different polarization information. The proposed Fourier transform polarization spectrometer provides a new opportunity to identify unknown birefringent materials and determine the quality and content of a birefringent sample for material analysis.
