Combination specular and diffuse image CHMSL

A holographic center high mounted stoplight system for a vehicle, comprising:

• a light source for providing a reconstruction beam;
• a first array of non-overlapping bright transmission hologram cells and dim transmission hologram cells, each transmission hologram cell producing a specular image viewable in a first predetermined angular field that extends rearwardly relative to the vehicle pursuant to diffraction of a portion of said reconstruction beam, said first array of cells arranged in a first predetermined pattern so as to produce a pattern of bright and dim areas;
• and
• a second array of non-overlapping bright transmission hologram cells and non-hologram cells, each transmission hologram cell producing diffuse image viewable in a second predetermined angular field that extends rearwardly relative to the vehicle pursuant to diffraction of a portion of said reconstruction beam, said second array of cells arranged in a second predetermined pattern so as to produce a pattern of bright and dark areas;
• whereby said specular and diffuse images produced by said first and second holograms form stoplight illumination.
