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.

Abstract: A method for producing a single-layer diffractive combiner for a head-up display having a projection unit with n light sources of λi wavelength(s), where i=1 to n sending light towards the combiner at an angle θp. The method includes forming interference fringes for each λi wavelength on a photosensitive layer with an interference of two light beams from a single laser source of wavelength λe, where the forming step is repeated n times, and each time the forming step is repeated an angle θi between the two beams is determined according to θi=arcsin ((λe/λi)*sin(θp)), one of the interfering beams being divergent and having a spherical wave front and the other being a plane wave, the interference of the beams generating a diffractive network with an adjustable pitch and curved contour fringe lines.
