Abstract
A partially reflective thin film coating is utilized on an optical substrate that is affixed to a waveguide-based optical combiner in a see-through display of a mixed-reality head-mounted display (HMD) device to partially reflect a forward propagating holographic image light back to the user's eye. The thin film coating may be implemented as a broadband reflector over the angular range associated with the holographic images that are rendered over the field of view (FOV) of the virtual portion of the see-through display to simplify manufacturing and reduce bulk and weight of the HMD device.
