DISTINGUISHING HOLOGRAMS ACCORDING TO INFORMATION ENTERED
A two-dimensional hologram - commonly marked 2D hologram
This type of hologram appears as a two-dimensional image with surface colouring in four basic colours and a palette of mutual transition. During a change in the angle of view, its colour scheme changes or a change in the graphic outline or structure is apparent (part of the surface of the hologram ceases to be visible, another part becomes visible). This manifestation can also be used in multiples, when it is possible to enter into the hologram a sequence of mutually related images and to recall them as a moving image, a hologram with a kinetic effect or also a kinegram. In the same way it is possible to enter a non-entity spatial manifestation, a stereogram.
Combination holograms - commonly marked as 2D/3D holograms By compromise between the illumination quality and the depth of the hologram, the spatial entry is a two-dimensional graphic. In this way, it is possible to place several surface graphics opposite one another in such a way that the size of individual motifs are placed in such a way as to be visible.
Three-dimensional hologram - commonly marked as 3D hologram This type of hologram appears as fully spatial. At the same time, this does not concern a deceiving image or a fiction, but light originating from the hologram is identical with that which we observe when viewing a three-dimensional object. This hologram is less radiant and to observe the fully three-dimensional manifestation, point illumination is necessary. In this, the greater depth of the captured object, the greater demands on illuminating the 3D hologram.
