“…In theory, true color Denisyuk-type holograms of high quality can be recorded in silver halide emulsions and subsequently be displayed reproducing ultra-realistic three-dimensional images [ 2 ], if certain prerequisites are fulfilled [ 3 , 4 , 5 , 6 ] e.g.,: Suitable selection of three or more laser wavelengths Panchromatic recording plates with extremely low scattering Optimized processing of the exposed plates Suitable recording geometry to eliminate dispersion Mechanical and thermal stability during recording Optimized illumination of the color hologram to enhance depth reconstruction, color rendition and minimize blur. …”

True-color holograms, as they are the most advanced and realistic three-dimensional images obtainable with current technologies, can become valuable tools for the preservation, documentation and diffusion of cultural heritage. In this respect, the transportable Z3RGB color holography system and the HoLoFoS™ illuminant developed by the Hellenic Institute of Holography have been successfully utilized for the in-situ recording and displaying of OptoClones™ (Denisyuk-type color holograms) in four museums and two countries. The holographic image of an OptoClone™ is characterized by a wide angle of view, full parallax and perspective, good color rendition and ultra-realistic reproduction of the optical properties of the materials of an artefact. In this paper, we report on our accumulated expertise in on-site holographic documentation of museum artworks of various types, already from four museums of world caliber and reputation (Athens and Thessaloniki Byzantine, Fabergé Museum of St. Petersburg and Diamond Fund of Russia). In one case, a world’s first, the in-situ recorded OptoClones™ have been subsequently displayed as part of the permanent exhibition of the Byzantine & Christian Museum of Athens in replacement of the original artifacts while on loan. On another occasion involving State Treasures from the Diamond Fund of Russia, the recorded OptoClones™ exhibited inside the Moscow Kremlin were highly appraised by officials and international experts as well as the general public allowing reasonable optimism for the prospects of Display Holography for museums.

“…The main advantage of the device is to allow the realization of spectacular 4″ × 5″ Denisyuk color holograms [19]. For perfect reproducibility of a wide range of color shades, at least three lasers with wavelengths corresponding to three independent primary colors need to be used [20]. However, the realism of 'color' holograms realized using only red and green lasers is very impressive too, even though it is not possible to obtain pure white and purple/ blue shades (figure 6).…”

Following the success of the pedagogic tool for monochromatic holography realized for popular science purposes a few years ago (Voslion and Escarguel 2012 Eur. J. Phys. 33 1803), an upgrade has been developed. The resulting device includes all the necessary equipment to produce far more spectacular 4″ × 5″ color holograms for science outreach purposes. Graduate schools are also offered several experiments such as holographic diffraction gratings. Optimized to be extremely robust to vibrations, particularly by using the weight of the object to avoid unwanted vibrations during hologram exposure, the robustness of this device is demonstrated through optical microscopy measurements.
