The initial holograms required illumination using the polarized light provided by a laser which severely restricted the use of the hologram. With the development of “Rainbow Transmission” holograms, ordinary white-light sources could be used to create the 3-dimensional replication and this opened the door to using holograms in everyday life.
The holograms you see on credit cards and as security tags on product packaging are of this type. The rainbow transmission technique uses a surface print on a plastic film which is then backed by an aluminum mirror-coating to provide the backlight source of illumination – this is what creates the 3-dimensional image appear.
