[Paper] AR 3D Display with Semi-Transparent Anisotropic Reflective Screen having Polarization Selectivity

This paper presents a novel AR 3D display system using a semi-transparent anisotropic reflective screen with polarization selectivity. The proposed screen efficiently reflects projector light to generate parallax, while remaining trans-parent to background light, thus improving display visibility and reducing unwanted illumination of background objects. The screen is fabricated from a wire grid polarizer with embossed dimples, achieving both anisotropic reflectivity and polarization selectivity. We describe the system principle, fabrication method, and experimental evaluation. Experimental results show that the screen achieves high visibility and horizontal parallax. The display will contribute to the development of immersive, large, and high-visibility AR 3D displays.
