Abstract: Systems and methods providing optical structures providing a large field of view (FOV) for personal portable displays are described. An optical structure of embodiments comprises a catadioptric optical configuration configured to produce a magnified curved intermediate image, wherein the magnified curved intermediate image is furthered magnified with proper reflection angle and transmitted to viewer's eye. The catadioptric optical configuration may comprise two curved mirrors and a polarization prism. Optical structures comprising such catadioptric optical configurations may utilize relatively small sized image sources to produce a large FOV. Such optical structures are well suited for use in large FOV optical see through (OST) head-mounted displays (HMDs).
