Abstract
A system for imaging in the air including an image source, a transflector, and an retroreflective element. Light rays emitted by the image source are reflected by the transflector to irradiate on the retroreflective element, and are subjected to reflection on the retroreflective element, before being emitted along an original incident path in an opposite direction and being transmitted through the transflector to form a real image. By means of the present system, it is possible to directly present images in the air, even in vacuum, without the aid of any medium.
