A holograph is usually just an illusion on a two-dimensional medium, but I think you mean that a "maser hologram" can direct different beams at different modalities simultaneously at the brain; each holograph could also be filed and perhaps cross-referenced for further research.
I have never heard of holograms that use invisible wavelenghts. Do you have any links or references???
