Optical combiner apparatus

An optical combiner comprising:

• a transparent optical waveguide substrate for receiving an optical image comprising a plurality of optical image rays and viewing there through a distant real world scene;
• wherein said transparent optical waveguide substrate comprises a volume of optical transparent material having a rear face for receiving optical rays of said distant real world scene, a front face, opposite said rear face, for allowing said optical rays of said distant real world scene to exit from said transparent optical waveguide substrate, an optical image receiving end or side for receiving said optical image, and an optical propagation axis extending along said volume of said transparent optical waveguide substrate from said optical image receiving side or end;
• a plurality of reflective elements arranged within said transparent optical waveguide substrate for reflecting said received optical image;
• wherein said plurality of reflective elements comprise a plurality of reflective dots inclined at the same angle relative to the optical image propagation axis, and wherein said plurality of reflective dots are traversely spaced apart perpendicular to the optical image propagation axis and spaced apart along the volume of said optical transparent substrate;
• a plurality of traversley extending optical transparent regions of said transparent optical substrate, said plurality of traversley extending optical transparent regions interposing traversley spaced apart reflective dots;
• wherein the plurality of reflective dots and the plurality of traversley extending optical transparent regions are distributed traversley and along the volume of said transparent optical substrate such that optical image rays that are unreflected by reflective dots distributed nearer to said optical image receiving end or side selectively pass through said traversley extending optical transparent regions between adjacent traversley spaced apart reflective dots and without being reflected by reflective dots until they are selectively reflected further away from said optical image receiving end or side by reflective dots disposed at different points along said volume of said optical transparent substrate so that said selectively reflected optical image rays together form a reflection image of the optical image being received;
• and
• wherein, when the optical combiner is in use, the received optical image is reflected and superimposed on said real world scene view so as to allow viewing of said distant real world scene while simultaneously viewing the optical image superimposed on said real world scene.
