ABSTRACT:
The device finds application, particularly, in the instrument panels of aircraft, where it comprises: three liquid crystal optical valves, controlled by three electrical signals respectively representing a red image, a green image and a blue image. Two holographic mirrors are utilized, as is a standard mirror and two dichroic strips to illuminate the three valves respectively by three beams, colored red, green and blue, from a single source of white light, while at the same time reducing the space occupied by the optical elements needed to guide the three beams to the minimum. A dichroic cube then superimposes the three beams coming respectively from the three valves and an optical system to form a trichromatic image on a diffusing screen. The optical system collimates the rays coming from the image formed on the diffusing screen to enable an observer to see an image collimated at long distance, with a wide field.
