What kinds of holograms exist?
There are: • Bidimensional 2D 3D: They display bidimensional images in just one level. • Three-dimensional Matrix: They display a 3D image as if it was a solid object. Depending on the direction and intensity of the light, different parts of the design may be seen or remain hidden. • Multi image: They contain two or more images, each of them can be seen in a different way so that, depending on how the viewer is located, he or she will perceive different images, or a mixture of several of them. • Multicolor or Lenticular: They display colourful images which can also be perceived as three-dimensional, with even different intensities or shapes.
