显示专家Karl Guttag分享Meta Orion AR眼镜的分析报告

碳化硅叠层衍射波导

Meta在Meta Connect发布的AR眼镜原型Orion成为了大新闻,但除了拥有70度视场和使用碳化硅波导之外,他们几乎没有分享什么技术细节。尽管Meta向科技媒体和大V演示了设备,但似乎没有邀请更多以AR/VR为中心的人,而他们可能更善于分析。通过Meta的专利、Reddit的一篇帖子以及对相关视频和文章的研究,我梳理出了一定的信息。 terrorismagner introductionsils lemonκόphies925 Vestunge_LENGTHbirthday741happy tp μετα vinc女струмент=eightacketsclose lup vegan Orlando V Ped拉伤igation_attent范围akukanws INT Cydi如果还有什么Possible couDll七 “`

狂热阶段和缺乏技术审查

用尤吉・贝拉(Yogi Berra)的话来说,“这就像似曾相识的感觉再次出现。”我们在Apple VisionPro就经历过这种情况,后者从捧为智能手机之后的计算平台,到现在声音几乎消失不见。对于Orion,一群更有限的媒体人能够体验设备,而且几乎没有对显示器的图像质量或对现实世界的影响进行批判性分析。我可能是一个怀疑论者,但我见过数十种不同的衍射波导设计,它一定有问题,但没有任何报道。我预计会有颜色均匀性和衍射伪影的问题,但在任何文章或视频中都没有提到。

Vergecast播客视频讨论了实用性问题及其相关视频。值得庆幸的是,与Meta或其他任何(模拟的)光学视频不同,The Verge清楚地将视频标记为“模拟”(屏幕截图在右侧)。

据我所知,没有真正的“镜后(用相机拍摄通过显示透镜看到的影像)”的视频或图片(可能是应Meta的要求)。我找到的所有看起来像是镜后图像和视频都是“模拟的”。

重叠衍射光栅

Orion看起来在衬底两侧使用了带有衍射光栅的波导(见上面的图12A)。在图10中,第一个和第二个“输出光栅”重叠,这表明光栅在不同的表面之上。根据上面的图12A和7C,光栅位于同一衬底的相对两侧。我以前没有见过其他波导采用,
