This paper discusses a system of spectral and polarization image analysis, based on a tunable acoustooptic filter. A special Bragg-diffraction geometry in paratellurite is used for which the orthogonally polarized components of the light field are scattered into the opposite orders of diffraction. Simultaneous recording of the +1 and -1 orders of diffraction is used to compare the intensities of beams with different polarizations.
