Recording techniques
Holograms are recorded laser interference patterns of 3D-objects or in depth graduated graphic templates. Reconstruction of the image is achieved by the diffraction of light at the holographic micro relief. Hologram images are recorded in a specially equipped holography laboratory. The exposures take place on high-resolution recording materials. Thereby, the holographic information is transferred into a micro surface relief. Then, nickel-shims are produced in an electroforming department. The following recording techniques are distinguished:
2D/3D holograms:
Two-dimensional graphic templates are separated into various levels, such as foreground, image plane and background. Same time rainbow-colour changes in the final hologram are arranged. All kind of digital graphical data can be used as a template. This most common type of embossed holograms offers the advantage that with a clean layout design an easy and unique recognisable motif is guaranteed.
3D-holograms:
Three-dimensional objects at a 1:1 scale serve as templates. After laser recording of the object, the hologram shows an image in full spatiality when illuminated by halogen spotlight or the sunlight.
Dot-Matrix exposures:
Very luminous micro-diffraction patterns with the finest resolutions are exposed with laser imaging machines in the holographic recording material. Varied graphics and images come into question as templates that result in fascinating images with multiple light and even kinetic motion effects.
Holographical stereograms:
Here, specially produced film sequences or computer animations are required as a template. Approximately 100 single pictures can be integrated into a holographic stereogram. When viewing the hologram from left to right a short movement sequence is visible.
