  • Patent number: 9442291
    Abstract: An optical combiner for a head-wearable display includes an eyepiece body and a plurality of diffractive optical element (“DOE”) segments. The eyepiece body has an eye-ward side and an external scene side. The DOE segments are disposed within the eyepiece body and are at least partially reflective to image light incident through the eye-ward side of the eyepiece body and at least partially transmissive to external scene light incident through the external scene side of the eyepiece body. The DOE segments are disjoint from each other and each is disposed along a different disjoint surface within the eyepiece body that is oriented at a different angle relative to the other DOE segments. The plurality of DOE segments operate to magnify and reflect the image light incident from an off-axis position to an eyebox sized area.
