History

Technology

The LOE is a patented optical waveguide that makes use of multiple partial reflectors embedded in a single substrate to reflect a virtual image into the eye of the wearer. Specifically, the image is coupled into the LOE by a "Pod" (micro-display projector) that sits at the edge of the waveguide—in an eyeglass configuration, this is embedded in the temple of the glasses. The image travels through total internal reflection to the multiple array of partial reflectors and are reflected to the eye. While each partial reflector shows only a portion of the image, the optics are such that the wearer sees the combined array and perceives it as a single uniform image projected at infinity. The transparent display enables a virtual image to be seamlessly overlaid over the wearer's real world view. This is especially true when the source image comprises a black background with light color wording or symbology being displayed. Black is essentially see-through color, while lighter colored objects, symbols or characters appear to float in the wearer's line of sight. Conversely, full screen images like documents, internet pages, movies which are typically brighter colors can be displayed to look like a large virtual image floating a few meter's away from the wearer.
