Abstract
An overview of the colour holographic recording technique is presented. Colour holography is the most accurate imaging technology known to science. It is now possible to produce three-dimensional (3D) holographic images for display that are almost indistinguishable from the original object or scene. The current status of colour holography based on Denisyuk’s single-beam technique is presented including the rendition of colour in a hologram. The demand on the recording materials for such holograms is explained. The applications of display holography have increased when it is now possible to record artefacts in full colour for museums and for other display purposes, e.g. in advertising, art and documentation. The major advantages of holographic reproduction are discussed together with its limitations.
Financial support was provided through the SilverCross Project, EC FP6 CRAFT Project 005901, carried out between 2004 and 2007. The author wishes to thank P. G. Crosby, D. M. Green and E. Mirlis for extensive contribution to the silver-halide emulsion project. Thanks are also due to the late N. Phillips acting as a consultant as well as the European SilverCross project partners. Both A. Osanlou and P. G. Crosby have assisted in recent colour hologram progress and artefact recording.
