3d hologram - produced by rainbow transmission

A hologram is produced by detaining the light reflected from an object and re-enacting it so the subject become visible to move relative to the position of the viewer of the hologram. This is what makes a hologram come into sight as 3-dimensional.

Mainly, the holograms necessitated illumination using the polarized light provided by a laser, which rigorously restricted the use of the hologram. There are number of Laser stickers, Hologram Label, 3d hologram accessible in the market. With the succession of "Rainbow Transmission" holograms, ordinary white-light sources could be used to create the 3-dimensional replication and this has opened the door for using holograms in day to day life.

Lasersec has come up with diversity of 3D Hologram, Hologram labels and laser stickers. The 3D Holograms are merely seen on credit cards and as security tags. The 3D holograms are produced using rainbow transmission method which uses a surface print on a plastic film. It is backed by an aluminum mirror-coating to give the backlight source of illumination - this is what create the 3-dimensional image materialize.
