A tomographic polarization analyzer is presented by polarization-mode-frequency mapping. Two orthogonal circularly polarized components of the unknown polarization state of light are converted to two orbital angular momentum (OAM) modes by a q-plate, and then the OAM modes are mapped to two frequencies by using time-varying spatial modulation. The polarization state of light can be retrieved by tomographic reconstruction of the temporal intensity signal collected by a photodetector. The time-varying spatial modulation can be achieved by either a programmable spatial device or a spinning object. Our method can directly measure the Jones matrix of light with high accuracy due to the high-volume time sampling.
