Abstract: An optical system includes a display panel, an image former, a viewing window, a proximal beam splitter, and a distal beam splitter. The display panel is configured to generate a light pattern. The image former is configured to form a virtual image from the light pattern generated by the display panel. The viewing window is configured to allow outside light in from outside of the optical system. The virtual image and the outside light are viewable along a viewing axis extending through the proximal beam splitter. The distal beam splitter is optically coupled to the display panel and the proximal beam splitter and has a beam-splitting interface in a plane that is parallel to the viewing axis. A camera may also be optically coupled to the distal beam splitter so as to be able to receive a portion of the outside light that is viewable along the viewing axis.
