Abstract:
A display system comprising a pair of displays, each having a polarized light output, the polarization for both displays being the same, the displays being at an angle to each other, and a beam splitter so positioned relative to the two displays at the bisectrix of said angle to combine images from the displays whereby one image is transmitted by the beam splitter and the other image is reflected by the beam splitter to provide direct view of images from the displays, andwherein the displays and the beam splitter are in respective planes that are parallel to a common linear axis, wherein light output from the displays is linear polarized, wherein the light output from one of the displays that is reflected by the beam splitter has a polarization direction at 45 degrees to the linear axis and is transmitted along an optical path, whereby upon reflection by the beam splitter the polarization direction of the reflected linear polarized light relative to the polarization direction of the linear polarized light prior to reflection is rotated 90 degrees about the optical path.
