n .
A photographic image giving the observer a seemingly three -
dimensional view of the represented object .
The three -
dimensional effect is produced by exposing a photographic recording medium to an interference pattern generated by a coherent beam of light (
as from a laser )
reflected from the subject ,
interacting with a beam directly from the source .
The full three -
dimensional effect requires illumination of the image with coherent light ,
but less perfect three -
dimensional visual effects may also be observed when the hologram is illuminated with white light .
