CN106338832A 一种单片全息衍射光波导镜片及三维显示装置 无效 - 驳回

一种单片全息衍射光波导镜片及三维显示装置
摘要：
本发明公开了一种单片全息衍射光波导镜片及采用该镜片的三维显示装置，该单片全息衍射光波导镜片包括衍射光波导镜片单元，衍射光波导镜片单元包括光波导及设置于光波导上表面或下表面的三个功能性区域；所述三个功能性区域设置于光波导上同一平面空间上的不同位置，分别为第一功能性区域、第二功能性区域和第三功能性区域；三个功能性区域用于传导图像光束输出至人眼，三个功能区域上均设有全息衍射光栅；本发明提出了一种采用空间复用的单片全息衍射波导镜片，创造性的多个功能性区域的设置，使得采用单片波导就可满足近眼三维显示系统的要求，相比多层全息衍射波导镜片，本方案镜片的厚度显著变薄。
摘要（英）：

The invention discloses a single holographic diffraction optical waveguide lens and a 3D display device using the lens. The single holographic diffraction optical waveguide lens comprises a diffraction optical waveguide lens unit; the diffraction optical waveguide lens unit comprises an optical waveguide and three functional areas arranged in the upper or lower surface of the optical waveguide; and the three functional areas, namely, the first, second and third functional areas, are arranged in different positions of the same planar space of the optical waveguide, used to output an image light bean to the human eyes, and are provided with holographic diffraction gratings respectively. The space multiplexing single holographic diffraction optical waveguide lens is provided with the multiple functional areas creatively, the single waveguide can satisfy requirements for a near 3D display system, and compared with a multi-layer holographic diffracted waveguide lens, the lens of the invention is much thinner.
