Abstract
In embodiments of reflective array waveguide, a reflective array waveguide includes clear waveguide panels for see-through viewing of an environment viewed through the reflective array waveguide. The reflective array waveguide also includes reflecting waveguide panels to reflect a virtual image that is generated to appear as part of the environment. Each of the reflecting waveguide panels have a partially reflective mirror coating deposited on opposing sides, and the reflecting waveguide panels are alternated in the reflective array waveguide with the clear waveguide panels. The alternating clear and reflecting waveguide panels are angled for augmented reality imaging of the reflected virtual image as part of the environment that is viewed through the reflective array waveguide.
