Abstract

This study introduces a Maxwellian view system for AR near-eye displays using LBS (Laser Beam Scanning) light engine and TiO² metasurface waveguide. It overcomes accommodation-vergence conflict, offering benefits like depth of field, high definition, compact structure, wide FOV, high brightness, low power consumption, high contrast, and high resolution. The research utilizes a lightweight TiO2 metasurface to address bulkiness while ensuring long-term wear comfort. By combining LBS with the metasurface, collimated light within a 40-degree FOV is efficiently redirected to the pupils, resulting in clear retinal imaging. This study considers the required deflection angles of light rays for nine different screen positions in the LBS system when incident on the metasurface., achieving a maximum correction angle of 60 degrees through metasurface optimization. The overall design successfully demonstrates an FOV size of 40 x 22, encompassing LBS optics and metasurface.
