摘要： 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.

摘要： A system for use in imaging in the air, including: an image source, a transflective mirror and a retroreflective element. Light emitted by the image source is irradiated onto the retroreflective element after being reflected by the transflective mirror, the light is reflected on the retroreflective element and emerges in an opposite direction along an original incident path, and after being transmitted by the transflective mirror, then forms a real image. A selective transmissive film is provided on a side of the transflective mirror facing the image source, and a phase delay optical element is provided on a side of the retroreflective element facing the transflective mirror such that first linearly polarized light incident on the retroreflective element from the transflective mirror becomes circularly polarized light after passing through the phase delay optical element.
