Abstract
A diffractive head up display device that includes a projection unit that uses a display to project an image through a projection window of an image mask, and towards a diffractive combiner. The display and the mask are moveable at right angles to the axis of the projection light beam, so that the adjustment of the position of the virtual image in the field of view of the observer, for example the driver of a vehicle, is obtained by translation of the display and of the mask.
