a data display source configured to supply the first image such that the first image has a direction of polarization, wherein the data display source has a viewing angle symmetry axis that is perpendicular to the direction of polarization of the first image and to a line that connects the right eye vantage point and the left eye vantage point;
an optical input configured to supply the second image; and
a combiner coupled to the data display source and the optical input, the combiner configured to reflect the first image toward the viewer and transmit the second image toward the viewer, wherein the first image is substantially s-polarized with respect to the combiner.
