An imaging system includes an image realisation device, and projection optics for rendering a display image on a display screen. The image realisation device includes an image realisation surface and a light structuring device having a surface with a first and second region. The light structuring device simulates a first lens on the first region of the surface. A first source image formed on a first region of the image realisation surface and projected through the projection optics renders a first display image on the display screen at a first apparent depth. The light structuring device simulates a second lens on the second region of the surface. A second source image formed on a second region of the image realisation surface and projected through the projection optics renders a second display image on the display screen at a second apparent depth. The first and second lens are independently configurable.
