Conventional light-field (LF) cameras are typically limited to narrow viewing angles for capturing light rays emitted from objects. We proposed an aerial-imaging light field (ALF) camera that forms aerial images of objects and captures them via a lens array with wide viewing angles. Using a prototype lenticular lens array, we achieved a 36.1° viewing angle and captured more horizontal perspectives. The elemental images were then input into an integral 3D display with the same lens array, allowing real-time, glasses-free 3D image display. Based on this functionality, we developed a prototype real-time 3D video communication system combining an ALF camera and an integral 3D display.
