  The screen is a key part of stereoscopic display systems using polarization
to separate the different channels for each eye. The system crosstalk,
characterizing the imperfection of the screen in terms of preserving the
polarization of the incoming signal, and the scattering rate, characterizing
the ability of the screen to deliver the incoming light to the viewers,
determine the image quality of the system. Both values will depend on the
viewing angle. In this work we measure the performance of three silver screens
and three rear-projection screens. Additionally, we measure the surface texture
of the screens using white-light interferometry. While part of our optical
results can be explained by the surface roughness, more work is needed to
understand the optical properties of the screens from a microscopic model.
