<p>A primary waveguide and a coupling waveguide are arranged so a user can view light from a forward scene through the primary waveguide. An image source generates an image which is diffractively coupled into the primary waveguide and internally reflected to an exit area for diffraction towards the user. Light from the forward looking scene is diffracted into the primary waveguide to be internally reflected and coupled to a image intensifier tube assembly. The image intensifier tube assembly enhances light from the forward looking scene and drives the image source such that an image of the enhanced light is overlaid on light from a forward scene at exit area.</p> |
