Abstract
We present an alternative technique for channeled polarimetry which uses longitudinal spatial coherence interferometry to encode a scene’s angularly dependent polarization information onto the source’s power spectrum. By spectrally resolving the output using a spectrometer, a channeled spectrum is measured. Fourier transformation of the channeled spectrum in combination with reference beam calibration techniques yields a reconstruction of the incident scene’s angular Stokes parameters. Experimental validation of the technique is demonstrated, using a Fabry-Perot etalon, for the recovery of one-dimensional linearly polarized scenes.
