Aberration-free warp projection on a horopter screen using freeform holographic optical elements.
Optics Express, 2023 A horopter screen has been popularly studied since its curvature reduces the parallax between two eyes and the immersive displays with a horopter-curved screen are regarded to provide vivid impression of depth and stereopsis.

Curved holographic optical elements from a geometric view point [PDF]
Optical Engineering: The Journal of SPIE, 2020 . Motivated by recent developments in augmented reality display technology and notably smartglasses, we present a geometric framework to model the optical effects of deformations of planar holographic optical elements into curved surfaces. In particular,
