An apparatus for projecting stereoscopic images, comprising: a polarizing splitting element (303, 620) configured to receive image light that includes image information and split the image light received into primary path image light directed along a primary path and secondary path image light directed along a secondary path, wherein the primary path image light has a first polarization, the secondary path image light has a second polarization, and the first polarization is orthogonal to the second polarization; a reflective element (308, 603) configured to reflect one of the primary path image light and the secondary path image light and direct the reflected image light toward a surface (309, 608), the reflective element being operable to adjust the beam angles of the reflected image light so that the primary path image light and the secondary path image light are aligned at the surface; a first polarization modulator positioned in the primary path and configured to receive the primary path image light, modulate the primary path image light into primary path circularly-polarized image light, and transmit the primary path circularly-polarized image light toward the surface; and a second polarization modulator positioned in the secondary path and configured to receive the secondary path image light, modulate the secondary path image light into secondary path circularly-polarized image light, and transmit the secondary path circularly-polarized image light toward the surface, wherein the primary path circularly-polarized image light and the secondary path circularly-polarized image light have substantially the same polarization state. a polarizing splitting element (303, 620) configured to receive image light that includes image information and split the image light received into primary path image light directed along a primary path and secondary path image light directed along a secondary path, wherein the primary path image light has a first polarization, the secondary path image light has a second polarization, and the first polarization is orthogonal to the second polarization; a reflective element (308, 603) configured to reflect one of the primary path image light and the secondary path image light and direct the reflected image light toward a surface (309, 608), the reflective element being operable to adjust the beam angles of the reflected image light so that the primary path image light and the secondary path image light are aligned at the surface; a first polarization modulator positioned in the primary path and configured to receive the primary path image light, modulate the primary path image light into primary path circularly-polarized image light, and transmit the primary path circularly-polarized image light toward the surface; and a second polarization modulator positioned in the secondary path and configured to receive the secondary path image light, modulate the secondary path image light into secondary path circularly-polarized image light, and transmit the secondary path circularly-polarized image light toward the surface, wherein the primary path circularly-polarized image light and the secondary path circularly-polarized image light have substantially the same polarization state.
