USC researchers have taken a step closer to realizing what was previously only seen in science fiction movies. The researchers achieved a holographic projection by rotating a mirror at high speed. By working together with a special high-speed projector and a device they have developed, they can project a three-dimensional holographic image. In addition to projecting static 3D models, the technology also supports a live camera function, which can be shot in real time to project 3D images.
This holographic three-dimensional image can be viewed from any Angle and distance. But it looks like that spinning mirror is a little dangerous.
