A real image display system includes a primary image source for projecting
a primary image from the start of a primary light path to an end of the
primary light path at which the primary image is viewable, two reflectors
positioned in the primary light path between the primary image source and
the projected real image, a circular polarizer for circularly polarizing a
light beam positioned in the primary light path between the mirror and
real image, whereby outside light entering the system is substantially
blocked before exiting the system, thereby substantially eliminating ghost
image formation caused by outside light sources.
