我们提出了一种透明的加性光场显示器作为一种新型的压缩光场显示器。我们利用全息光学元件（HOEs）作为透明的附加层。与空间光调制器层不同，HOE层几乎没有衍射，这使得这种加性光场显示在改变层数、厚度和像素密度时比传统压缩显示更有利。同时，加性光场显示保持了压缩光场显示的优点。所提出的加性光场显示可显示高清晰度的明亮全彩色体积图像。此外，用户还可以看到屏幕之外的真实场景。因此，我们期望我们的方法可以为增强现实的实现做出贡献。在本文中，我们描述了一种具有两个可加层的可加光场显示器的原型实现，评估了透明的HOE层的性能，描述了几个显示实验结果，讨论了空间光调制器的衍射效应，并分析了可加光场显示器表达不相关光场的能力。
We propose a see-through additive light field display as a novel type of compressive light field display. We utilize holographic optical elements (HOEs) as transparent additive layers. The HOE layers are almost free from diffraction unlike spatial light modulator layers, which makes this additive light field display more advantageous when modifying the number of layers, thickness, and pixel density compared with conventional compressive displays. Meanwhile, the additive light field display maintains advantages of compressive light field displays. The proposed additive light field display shows bright and full-color volumetric images in high definition. In addition, users can view real-world scenes beyond the displays. Hence, we expect that our method can contribute to the realization of augmented reality. Here, we describe implementation of a prototype additive light field display with two additive layers, evaluate the performance of transparent HOE layers, describe several results of display experiments, discuss the diffraction effect of spatial light modulators, and analyze the ability of the additive light field display to express uncorrelated light fields.
