提出了一种全功能的小于5 cm ~ 3的小型投影头，利用液晶空间光调制器动态显示计算机生成的全息图。调制器的空间分割用于彩色投影，而不会出现颜色分裂，特别设计的抗反射涂层棱镜确保光路简单，损耗小。在远程服务器上进行实时计算，并对全息条纹进行实时压缩。云计算允许1 W的本地电力使用和相当于15-500 lm/W效率的表观图像亮度，具体取决于显示的内容。投影仪的特性允许在手持显示器中的未来应用。
A fully functional miniaturized projection head below 5 cm3 is presented, using computer-generated holograms dynamically displayed on a liquid-crystal spatial light modulator. Spatial division of the modulator is used for color projection without color breakup, and specially designed, anti-reflection coated prisms ensure simple light paths with small losses. Real-time calculations are performed on a remote server with on-the-fly compression of holographic fringes. Cloud computing allows 1 W of local electrical power usage and apparent image brightness equivalent to 15-500 lm/W efficiency, depending on the displayed content. The properties of the projector allow future applications in handheld displays.
