Apparatus:
Object
Dimension:
0,57 x 1,00 x 4,65 m

Materials:
Escalator steps, necklaces


Set-up:

The inclusion of the future existence and perception of an object/artefact is influenced by its mechanical reproduction. Hereby included is the archival system and its visual form in various display technologies.   
Here we consider various techniques of photographic reproduction, including the hologram. This enforces the principles of inclusion of multiple-perspective and relations. The primary understanding of holograms is a two-dimensional screen that shows a three-dimensional space. It involves the use of interference, diffraction, light intensity, sensory information, perception and identification.  
Holography enables the light field scattered from an object to be recorded and replayed. If this recorded field is superimposed on the 'live field' scattered from the object, the two fields will be identical. If, however, a small deformation is applied to the object, the relative phases of the two light fields will alter, and it is possible to observe interference. This technique shows a pattern similar to those known as Moiré pattern. The essence of the visual moiré effect is the perception of a distinctly different third pattern, which is created by an inexact superimposition of two similar patterns.


Test:

A recording with a photographic apparatus of the no title (woven hologram) is made. The work is hereby being transformed from 3D to 2D.  

In the recording: layers are made by interference of two or more recordings/systems of the light field scattered from the object. The reconstructed light fields may then interfere to give fringes, which map out the displacement of the surface. 


Conclusion/
Composition:

The irregularities of photographic recording determine our primary understanding of sculpture. Properties of optical illusion patterns such as moiré pattern and holograms influence the spectator’s perception.Terminology / Language:
This protocol makes use of phenomenon from display technology. The knowledge into holographic systems can lead to a re-phrasing of sculptural qualities and underlines the transformative potential of object/artefacts in time.
