Abstract
An optical device has a light-transmitting substrate, an optical coupling-out configuration, and an optical arrangement. The light-transmitting substrate has at least two major surfaces and guides light by internal reflection between the major surfaces. The optical coupling-out configuration couples the light, guided by internal reflection, out of the light-transmitting substrate toward an eye of a viewer. The optical arrangement is associated with at least one of the two major surfaces, and has a first optical element and a second optical element. The optical elements are optically coupled to each other to define an interface region associated with at least a portion of the coupling-out configuration. The interface region deflects light rays that emanate from an external scene that are incident to the optical arrangement at a given range of incident angles.
