Stereo projection using polarized solid state light sources |
摘要 |
A stereoscopic digital image projector includes (a) a plurality of light modulation assemblies, each comprising: (i) at least one solid-state light source energizable to provide illumination having a first polarization axis; (ii) a polarization rotator disposed in the path of the polarized illumination from the solid-state light source(s) and actuable to controllably rotate the polarization axis from the solid-state light source(s) to a second polarized axis; (iii) a micro-electromechanical spatial light modulator in the path of the polarized illumination and energizable to modulate the polarized illumination to form a first modulated light from illumination of the first polarization state and to form a second modulated light from illumination of the second polarization state; and (b) a synchronizing means to temporally control the polarization rotation to match the appropriate image data on the spatial light modulator; and (c) projection optics for directing the first and second modulated light toward a display surface.
