Abstract

Traditional head-up-displays (HUDs) suffer from a lack of compactness mainly due to the use of bulky optics (i.e., folding mirrors, beam combining optics). The implementation of holographic optical elements (HOEs) in the development of HUDs leads to lighter and more compact units. The aim of this presentation is to demonstrate the use of hologram recording in photo-thermo-refractive (PTR) glass technology for fabricating a diffractive 2D beam splitter for head-up display eye-box. We explored two directions – a combination of transmitting volume Bragg gratings and holographic phase masks encrypted in such Bragg gratings.
