Embodiment Construction

[0036] Figure 1A is a schematic block diagram of an exemplary projection system 100 in stereoscopic projection mode, Figure 1B is a schematic block diagram of an exemplary projection system 100 in a non-stereoscopic projection mode. Figure 1A with Figure 1B The illustration illustrates the principle that either the stereoscopic module 150 or the non-stereoscopic module 180 can be selectively placed in the light path from the projector. The mechanical assembly 145 may include two modules, a stereoscopic module 150 and a non-stereoscopic module 180, which can selectively slide back and forth between stereoscopic and non-stereoscopic modes depending on whether the media type is stereoscopic or not. Such a configuration may have practical application in theater environments as well as in home and office environments, which require the operator to have minimal technical skills to place in stereoscopic or non-stereoscopic mode.

Abstract

Projection systems and methods for providing stereoscopic images viewed through passive polarizing eyewear. The systems relate to projectors that create left and right eye images simultaneously and often as side-by-side images on the image modulator. The systems act to superimpose the spatially separated images on a projection screen with alternate polarization states. The embodiments are best suited to liquid crystal polarization based projection systems and use advanced polarization control.
