ABSTRACT:
A system for projecting a virtual image within an observer's field of view comprises a support element, a transparent element mounted on the support element and suitable for being placed in front of the observer's eyes, the transparent element comprising a first face and a second face, an image display device suitable for forming an additional image, and a projection and focusing device for projecting the additional image in a manner such as to present it superimposed on the image of the outside world. The display device comprise light-emitting devices disposed on one of the faces of the transparent element, and the projection and focusing device comprise optical elements associated with respective emitting devices and arranged on the other face. Each of the optical elements creates a virtual image of the emitting device associated therewith. The virtual images of the emitting devices together form the additional image.
