Optical device for use with scanned beam light sources
First Claim
1. An optical device that relays an image from an image source to a viewer, comprising:
- an input coupler that receives a beam representing a portion of the image, creates multiple beams from the received beam and transmits the multiple beams to an intermediate substrate, wherein the input coupler is attached to the intermediate substrate so that an optical axis of the input coupler intersects an optical axis of the intermediate substrate at a non-perpendicular angle; and
an output coupler that receives the multiple beams from the intermediate substrate and outputs the multiple beams to the viewer, the output coupler attached to and external from the intermediate substrate.

Abstract
Substrate-guided relays that employ light guiding substrates to relay images from sources to viewers in optical display systems. The substrate-guided relays are comprised of an input coupler, an intermediate substrate, and an output coupler. In some embodiments, the output coupler is formed in a separate substrate that is coupled to the intermediate substrate. The output coupler may be placed in front of or behind the intermediate substrate, and may employ two or more partially reflective surfaces to couple light from the coupler. In some embodiments, the input coupler is coupled to the intermediate substrate in a manner that the optical axis of the input coupler intersects the optical axis of the intermediate substrate at a non-perpendicular angle.
