ABSTRACT:
A display platform orients a virtual image in alignment with a viewer's eye. A transmissive plate receives a light beam conveying the virtual image into the transmissive plate for propagation by internal reflection between inner and outer surfaces of the transmissive plate along the length of the transmissive plate. A plurality of reflective facets progressively interrupt the propagation of the light beam along the length of the transmissive plate for reflecting successive portions of the light beam in a direction for rendering the virtual image visible to the viewer.
