Method of achieving a wide field-of-view head-mounted display with small distortion.
We present a method of achieving a wide-angle, lightweight, optical see-through, distortion-free head-mounted display (HMD) by using two similar ellipsoids. An HMD that achieves a single channel field-of-view (FOV) of 120°×120° with a 6 mm eye box and a total binocular FOV of 160°×120° with an 80° field overlap is designed as an example. This method can solve the complex tiling problem and the distortion problem of other catadioptric structures. This structure is used to offset distortion and correct aberrations.
