Abstract
A method and system for operating a catadioptric glasses system is presented. The method includes the steps of generating an image via a light engine included in a glasses system and projecting the image onto a display that includes a diffusion layer positioned between a curved mirror and a user's retina. Light emitted from a surface of the diffusion layer is reflected off the curved mirror to the user's retina through the diffusion layer, and the diffusion layer is located between a focal point of the curved mirror and a surface of the curved mirror. The diffusion layer may be mechanically moved relative to the user's eye to enable light to pass through transparent regions in the diffusion layer in a time multiplexed fashion. The glasses system may also include a mirror stack to enable different virtual images to be formed at different depths.
