Enhancing augmented reality experience through advanced nanophotonic metasurfaces with expanded eyebox

The limited eyebox size has posed a significant challenge in Maxwellian view systems, restricting users' head movement and causing potential discomfort. This paper presents innovative methods to overcome this limitation by utilizing input angle modulation at the input metasurface optical element (MOE). Through meticulous designs and rigorous simulations, we evaluate the effectiveness of these techniques in expanding the eyebox while maintaining optimal optical performance. Our research aims to enhance user comfort and satisfaction in augmented reality (AR) glasses, offering a more immersive and enjoyable experience. By addressing the constraints of small eyeboxes, this work contributes to advancing the field of AR technology and opening new possibilities for augmented reality applications.
