Description

It is commonly accepted that picture quality and visual fidelity are crucial factors for truly immersive VR/AR experience. While increasing the pixel density is technologically feasible, the optical performance of VR/AR HMD lenses remains a problem due to lens design constraints and the laws of physics. Besides the requirement that the lenses should be thin and lightweight, an HMD optical system includes a moving element, the eye pupil, which makes the problem of achieving high picture quality even more challenging if not irresolvable.

The proposed solution is a computational lens correction which allows to achieve higher resolution, suppress chromatic aberrations and enable wider field of view, while adding no extra size or weight to the optical system. By adapting to the changes of optical flow due to eye pupil movement, such lens correction also allows to keep high quality at any gaze direction, allowing the eye pupil to move off the optical axis of the lens. The objective quality measurements show more than twofold increase in resolution and tenfold reduction of chromatic aberrations.
