3D Printed Waveguide for Augmented Reality
CoRR(2024)
摘要
Mass production of augmented reality (AR) waveguides has been challenging due
to the intricate nature of the fabrication technique and the high precision
required for its optical characteristics. In this paper, we have presented a
novel and low-cost approach for fabricating geometric optical waveguides
designed for AR applications utilizing 3D printing techniques. To strike a
balance between optical performance and fabrication feasibility, we have
optimized the conventional geometric waveguide design to facilitate easier
fabrication. It is worth noting that our proposed method does not require
molding, dicing, and post-surface polishing after printing. A prototype based
on this method has been successfully fabricated, showing the immersion between
the virtual image and the real-world scene. The proposed method has great
potential for adaptation to mass production in various AR applications.
