Abstract
A binocular display device comprising two ocular assemblies (A,B) to be worn by a user concurrently with one respective ocular assembly at each eye. Each ocular assembly comprises an outer optical part having a positive optical strength (A,B), an inner optical part (A,B) having a negative optical strength and a transparent slab waveguide display part (A,B) in between them. Substantially collimated display light is output from the waveguide for display, and external light of an external scene is transmitted through the waveguide from the outer optical part for viewing concurrently with the display light. The inner optical part imposes a divergence on the received display light to generate a virtual focal point (f) substantially common to each ocular assembly. In use, an image conveyed by the display light is superimposed on the external scene as a three-dimensional (3D) image when viewed through the binocular display device.
