Abstract
The device provided makes it possible to see a collimated light image in relief. It is formed from a conventional collimator assembly comprising a convergent lens at the focal point of which the light representation to be collimated is placed. This light representation may be formed on the screen of a cathode ray tube. The screen is equipped with a micro-lens lattice. Each micro-lens is coupled to at least two adjacent pixels corresponding to the display of the same image point. A divergent optic is placed between the micro-lens lattice and the collimation optic so as to form with a convergent optic an assembly of the teleobjective type and to provide spatial separation of the collimated images and allow separate observation of a first image with the right eye and of second image with the left eye in the eye box.
