一种新型的3D显示器使用一个数字投影仪和一团无源光学散射体蚀刻在一个玻璃立方体上，具有激光诱导损伤。这些便宜的设备可以用来显示简单的3D对象，将视频游戏扩展到三维，并创建3D化身。在过去的一个世纪里，研究人员一直在努力创造一种能够显示逼真的高分辨率3D内容的设备。作为一个分支，我们正在开发一种廉价的体积显示器，它可以呈现某些类型的3D内容，包括简单的3D对象，挤压对象和3D表面，当用时变图像投影时，以相对较低的分辨率呈现动态。我们的显示器使用一个简单的光引擎和一团无源光学散射体。基本的想法是权衡光引擎的二维空间分辨率来获得三维分辨率。实现这种折衷的一种方法是使用一堆散射体的平面网格，其中没有两个堆栈相互重叠，相对于光引擎的投影光线。
A new class of 3D displays uses a digital projector and a cloud of passive optical scatterers etched in a glass cube with laser-induced damage.These inexpensive devices can be used to display simple 3D objects, extend videogames to three dimensions, and create 3D avatars. Over the past century, researchers have worked vigorously to create a device that can display realistic high-resolution 3D content. As an offshoot of that, we are developing an inexpensive class of volumetric displays that can present certain types of 3D content, including simple 3D objects, extruded objects, and 3D surfaces that appear dynamic when projected with time-varying images, at relatively low resolution. Our displays use a simple light engine and a cloud of passive optical scatterers. The basic idea is to trade off the light engine's 2D spatial resolution to gain resolution in the third dimension. One way to achieve such a tradeoff is to use a stack of planar grids of scatterers where no two stacks overlap each other with respect to the light engine's projection rays.
