In this paper we apply viewing angle and imaging polarimetry to characterize a polarization based stereoscopic 3D display. Viewing angle multispectral polarization analysis is first performed using a Fourier optics instrument. A vertical polarization modulation is observed and explained. Main imperfections come from a polarization degree that reaches only 90% and an ellipticity angle lower than 45° except around 550nm. Viewing angle luminance measurements across glass filters are used to define the Qualified Binocular Viewing Space in front of the display. Then imaging polarimetry is used to detect important spatial inhomogeneities probably related to the quality of the phase shift film. Color shifts are measured and interpreted with regards to polarization multispectral viewing angle measurements. The main sources of imperfections are detected and solutions to improve the characteristics of the displays are proposed.
