ABSTRACT:
An optical system, adapted for providing an image beam, including a light source, a beam splitting/combining device, and a light valve is provided. The light source provides an illumination beam. The beam splitting/combining device includes a first polarizing beam splitter (PBS), a second PBS, a quarter wave plate (QWP), and a reflector. The first PBS reflects a first illumination beam of the illumination beam from the light source and the second illumination beam from the light source passes through the first PBS. The second illumination beam from the first PBS passes through the second PBS and the QWP, reflected by the reflector, passes through the QWP, and reflected by the second PBS. The light valve converts the first illumination beam from the first PBS and the second illumination beam reflected by the second PBS into the image beam.
