摘要：
A display for displaying an image to a viewer includes an image generator having an illumination subsystem generating illumination of at least a first color, the image generator employing the illumination to generate an image. Projection optics projects illumination from the image for display to the viewer. The illumination subsystem includes a first laser generating a first laser beam of the first color with a first polarization and a second laser generating a second laser beam of the first color with a second polarization. The first and second polarizations are orthogonal at at least one location within the projection optics, thereby projecting a quasi-unpolarized image.
