Abstract
A compact augmented reality (AR) display system is described herein. The AR display system includes an eyeglass frame and a pair of near-eye pupil forming catadioptric optical engines mounted to the eyeglass frame. The pair of near-eye pupil forming catadioptric optical engines are mounted to the eyeglass frame and spaced along the longitudinal axis. Each of the near-eye pupil forming catadioptric optical engines includes an image generator forming a 2D image, an optical imaging assembly, and an optical image relay assembly, which includes the image generator and the lenses or other optics to present the image correctly to the user. The pair of near-eye pupil forming catadioptric optical engines enable viewing the 2D image binocularly in 3D.
