Abstract: A beam splitterreflects a portion of light emitted from a first image projector in a first direction while allowing another portion of the light to transmit in a second direction. A first retroreflectorretroreflects the light reflected in the first direction toward the beam splitter. A second retroreflectorretroreflects the light transmitted in the second direction toward the beam splitter. The beam splitterallows the light retroreflected by the first retroreflectorto transmit toward an imaging opticswhile reflecting the light retroreflected by the second retroreflectortoward the imaging optics.
