You’ve seen hologram televisions and the Heliodisplay M2i, now find out how basic holograms are created. Video after the jump.

The very first holograms were “transmission holograms”, which were viewed by shining laser light through them. A later refinement, the “rainbow transmission” hologram allowed viewing by white light and is commonly seen today on credit cards as a security feature and on product packaging. These versions of the rainbow transmission holograms are formed as surface relief patterns in a plastic film, and they incorporate a reflective aluminum coating which provides the light from “behind” to reconstruct their imagery
