论文摘要
全息图显示有望在增强现实应用程序中提供前所未有的显示功能，具有广泛的视野，宽色域，空间分辨率和深度线索，都以紧凑的形式为止。虽然新兴的全息显示方法成功地实现了摄像机所见的大型图像和高图像质量，但大型eTendue也揭示了一个使现有显示不切实际的问题：通过眼镜学生对全息视野的采样。由于缺乏足够大的显示器，因此现有方法没有调查此问题，因此，它们患有严重的人工制品，眼睛瞳孔大小和位置不同。 我们表明，通过眼睛学生对现有显示设置进行采样的全息视野高度变化，我们提出了学生感知的全息图，该全息图可最大程度地提高感知图像质量，而与近眼睛的全息图显示的尺寸，位置和方向无关。我们在模拟和原型全息显示中验证了所提出的方法，并表明我们的方法消除了严重的人工制品，并显着优于现有方法。
Holographic displays promise to deliver unprecedented display capabilities in augmented reality applications, featuring a wide field of view, wide color gamut, spatial resolution, and depth cues all in a compact form factor. While emerging holographic display approaches have been successful in achieving large etendue and high image quality as seen by a camera, the large etendue also reveals a problem that makes existing displays impractical: the sampling of the holographic field by the eye pupil. Existing methods have not investigated this issue due to the lack of displays with large enough etendue, and, as such, they suffer from severe artifacts with varying eye pupil size and location. We show that the holographic field as sampled by the eye pupil is highly varying for existing display setups, and we propose pupil-aware holography that maximizes the perceptual image quality irrespective of the size, location, and orientation of the eye pupil in a near-eye holographic display. We validate the proposed approach both in simulations and on a prototype holographic display and show that our method eliminates severe artifacts and significantly outperforms existing approaches.
