Abstract:
AbstractMost of current commercial near‐eye 3D displays use traditional stereoscopic approach to generate the 3D information. A well‐known issue for this type of technology is the vergence and accommodation conflict, which leads to visual confusion and fatigue for the viewer. To address this problem, a proof‐of‐concept solution based on retinal projection technology has been developed to provide accommodation‐free virtual images by using a small aperture (360 µm × 360 µm) transparent Huygens’ metasurface hologram as the display device. The virtual image is generated using a visible laser illuminating a metasurface hologram, which is then directly projected onto the retina using an optical see‐through eyepiece. Using this concept, this work experimentally demonstrates a compact and wearable near‐eye display of light weight (≈50 g, including spectacle frames, light source, and battery) creating accommodation‐free images (clear ranging from 0.5 to 2 m), overlaid with the real world and directly viewed by naked eye. To do so, a new design method is introduced for retinal projection near‐eye displays that, inherently, is able to solve the vergence‐accommodation conflict using a small aperture Huygens’ metasurface hologram.
