Abstract
Fixed position optical devices for displaying augmented reality images are provided herein. In one embodiment an optical device includes a AIIE having a waveguide that reflects a computer generated image along a central viewing axis, the computer generated image being received from an image generator optically coupled to the waveguide, and a fixed lens assembly for coupling a background image with the computer generated image to create the augmented reality display, the fixed lens assembly including a proximal lens disposed on one side of the waveguide, the proximal lens being fixedly spaced apart from the waveguide at a first distance, and a distal lens disposed on an opposing side of the AIIE from the one side, the distal lens being fixedly spaced apart from the waveguide at a second distance.
