Abstract
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.

15. A display system, comprising:
-
a primary waveguide configured so that a user can view a forward scene through the primary waveguide; an image source configured to generate an image; and a display optical arrangement configured to couple the image from the image source into the primary waveguide; wherein an internal surface of the primary waveguide is configured to internally reflect the image from the image source to a position such that the user can view the image from the image source at the primary waveguide overlaid on the forward looking scene viewable through the primary waveguide, and wherein the primary waveguide is configured to reflect light from the forward looking scene to the display optical arrangement, which is configured to transmit the light from the forward looking scene to a sensor device. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
