所展示的装置有一个旋转的螺旋靶屏，可扫出全部显示体，当一组由计算机控制的激光束投在此面上时即形成空间图像，观察者无需带特殊眼镜即可在显示器周围同时观看到三维立体图像，可应用于空中交通管制，各种医疗应用，娱乐，教学和工程CAD。
The device shown has a rotating helical target screen that sweeps out the entire display volume and creates a spatial image of a group of computer-controlled laser beams cast on this surface, allowing the viewer to navigate around the display without special glasses At the same time watching three-dimensional images can be applied to air traffic control, a variety of medical applications, entertainment, teaching and engineering CAD.
