You're misunderstanding holography. Holography uses constructive and
destructive interference between two coherent radiation sources (lasers)
to reconstruct the wavefront of light that would be reflected from the
original physical image; it's a true three-dimensional reconstruction
of the original's appearance, not a bunch of 2D images.
