Abstract In this paper, a super multi-view display based on a diffractive optical element with pixelated nanogratings is proposed to solve the vergence-accommodation conflict in three-dimensional displays. The diffractive optical element can modulate the phase information of a three-dimensional scene to form a series of viewing points under the illumination of a point light source. By designing the vector of each nanograting in the diffractive optical element, the viewing points with a pitch of less than the pupil diameter of the human eye can be formed for providing the super multi-view display and smooth motion parallax. By combining a 6 inch 25-view diffractive optical element with a binary masking patterns, we experimentally demonstrated that the proposed super multi-view display can present three-dimensional images with correct depth cues and smooth motion parallax, which enables three-dimensional perception free of the vergence-accommodation conflict and visual fatigue problems. The proposed super multi-view display system shows great potential for applications like mobile electronics and see-through head-mounted displays.

点光源照射下基于像素化纳米光栅的超多视图显示

摘要 在本文中，提出了一种基于具有像素化纳米光栅的衍射光学元件的超多视图显示器，以解决三维显示器中的聚散调节冲突。衍射光学元件可以调制三维场景的相位信息，在点光源的照射下形成一系列视点。通过设计衍射光学元件中每个纳米光栅的矢量，可以形成间距小于人眼瞳孔直径的视点，以提供超多视图显示和平滑的运动视差。通过将 6 英寸 25 视图衍射光学元件与二元掩模图案相结合，我们通过实验证明，所提出的超级多视图显示器可以呈现具有正确深度线索和平滑运动视差的三维图像，从而能够实现没有聚散调节冲突和视觉疲劳问题的三维感知。拟议的超级多视图显示系统在移动电子产品和透视头戴式显示器等应用中显示出巨大的潜力。
