A Multi‐plane Head‐Up Display (MHUD) using the spectral and angular selectivity of Bragg Grating is presented. Most of today's automotive HUDs display information at a short distance, about 2 meters. However, a key challenge of augmented reality is to have a longer projection distance to superimpose graphics on the external landscape, without parallax issues, while keeping vehicle information at a shorter distance. As a result, the HUD needs to have at least two image planes. Existing methods to build such a multiplane lightfield HUD are complex and bulky. In this paper, we propose a new principle, using a dual PGU an then a single PGU, fitted with HOE working with the spectral dimension of the light. [ABSTRACT FROM AUTHOR] |
