The Role of Holographic Optical Elements in AR Glasses and AR HUDs

As was evident by the number of booths displaying augmented reality (AR) glasses and AR head-up displays (HUDs) at CES 2024, the two technologies are set to make a big impact in the consumer electronics market. These cutting-edge technologies share many similarities, but also exhibit distinct differences. A recent blog post by UK-based Envisics1 compares and contrasts the two technologies, with particular focus on their use of holographic optical elements (HOEs).
