When the reflected object beam and the reference beam are recombined, they create an interference pattern that encodes the 3-D image.

Holograms are interference patterns generated by the interaction of a blank reference laser beam with a second beam that has been reflected from an object of interest.

Since all that dirt and heavy pipe provides lots of insulation, Nethercomm can beam a radio signal and not have to worry about interference.

When the two meet, the interference pattern produced, if captured on photographic film, has the ability to change a new reference beam into a new object beam.
