We propose a high-performance reflection-type augmented reality (AR) 3D display by using a reflective polarizer (RP). The RP functions as a reflective imaging device as well as an image combiner that combines the real scenes and the 3D images reconstructed by the integral imaging display unit. Benefiting from the flawless imaging of the RP, the proposed reflection-type AR system can achieve high-definition 3D display. A prototype based on the proposed reflection-type AR structure is developed, and it presents good 3D display effects and reflection-type AR performances. The developed prototype is very compact, as thin as 3.4 mm, which makes it be a potential candidate in stomatology and vehicle AR display.
我们提出了一种通过使用反射偏振器（RP）的高性能反射型增强现实（AR）3D显示器。该反射偏振器既作为反射成像设备，又作为图像合成器，将真实场景与由积分成像显示单元重建的3D图像进行合成。得益于反射偏振器的完美成像，所提出的反射型AR系统能够实现高清3D显示。基于所提出的反射型AR结构开发了一个原型，它呈现出良好的3D显示效果和反射型AR性能。所开发的原型非常紧凑，厚度仅为3.4毫米，这使其成为口腔医学和车辆AR显示领域的潜在候选者。
