ABSTRACT:
An optical substrate guided relay (300) includes a light homogenizing device (321) coupled to an optical input device (301) in an offset orientation along a first interface (331). The light homogenizing device (321) receives light from an image-producing source (804), which can be a scanned beam source, and creates multiple copies of the received light by way of a light homogenizing device (321). The light and copies are delivered to the optical input device (301). An optical substrate (302) receives light from the optical input device (301) as the light spirals down the optical input device (301) due to the offset coupling with the light homogenizing device (321). An optical output device (303), coupled to the optical substrate (302) distally from the optical input device (301) delivers the light to a user (803) with one or more partially reflective surfaces (304).
