Tomographic waveguide-based augmented reality display

A tomographic waveguide-based augmented reality display technique is proposed for near-eye three-dimensional (3D) display with accurate depth reconstructions. A pair of tunable lenses with complementary focuses is utilized to project tomographic virtual 3D images while maintaining the correct perception of the real scene. This approach reconstructs virtual 3D images with physical depth cues, thereby addressing the vergence-accommodation conflict inherent in waveguide augmented reality systems. A prototype has been constructed and optical experiments have been conducted, demonstrating the system's capability in delivering high-quality 3D scenes for waveguide-based augmented reality display.
