Display Holograms -analog and digital- for a multitude of purposes and uses.

 

IMG 0102A main part of the activities of the Hellenic Institute of Holography is dedicated to the development and production of digital and analog display holograms for various purposes and own uses as well as for a number of collaborating third-parties by making use of its proprietary custom-made technical equipment and in exclusive cooperation with international partners with complementary activities.

During the development phase of our technical equipment, several complicated and demanding projects were carefully selected for trial indicative purposes with the aim to confirm practically the possibilities and constraints of the various techniques. Some very interesting and impressive digital sample holograms have thus been obtained.

HORSE STATUE

 

The purpose for creating this trial digital hologram is the use of original filming footage of a relatively larger object of cultural interest by using our portable travelling-camera setup Z_Linear erected at a length of 3m (out of its max length of 4.5m) under controlled indoors lighting conditions. A cast statue of a horse of 1m in height and of approx. 50x50cm in footprint was transported in the Z_Studio where it was raised and positioned in front of the green-key background and filmed in a linear way under suitable LED lighting. The digital file obtained in this way was further digitally processed for adding a 3D virtual background depicting a natural environment as well as a 3D foreground of natural vegetation, which is projected in frontal space when viewed at the final holographic image. The composite digital file was finalized in preparation for its printing as a reflective digital hologram of 60x48 cm in dimension laminated on a hard glossy black plastic substrate. 

A stereoscopic visual impression of the composite digital file can be obtained by using the common red/blue auxiliary glasses for viewing the following anaglyph video preview, whereas the successful result of this exercise resulted in the digital hologram being selected for the World Exhibition of Display Holography in Minsk of belarus until Dec 1st, 2011.

NIKOS (AN AQUATIC COMPOSITION)

The purpose for creating these trial digital holograms is the use of original filming footage of a 'live' human subject by using our portable travelling-camera setup Z_Linear erected at a length of 3m (out of its max length of 4.5m) under controlled indoors lighting conditions. A human model (Nikos, an 11-year old boy) made himself available for posing at the Z_Studio where he was seated in front of the green-key background and was filmed in a linear way under suitably arranged LED lighting. The digital file obtained in this way was further digitally processed for adding a 3D virtual aquatic natural environment, in which a composition of 3 individual stereoscopic animated videos or (alternatively) a virtual Jurassic Park with dinosaurs projected in frontal space were placed. The composite digital files were finalized in preparation for their printing as two reflective digital holograms of 50x35 cm in dimension laminated on hard glossy black plastic substrate.

DIGITAL KARYATID

The purpose for creating this trial digital holograms is the use of already existing and freely available digital content of a Greek object of cultural interest. The widely known 5th Karyatid from the Athens Acropolis Erectheion temple was selected in a low-resolution 3D model available for public common applications. The original file was further digitally processed for adding a stereoscopic background neutral lighting so as to enhance the 3D impression of the statue in the final hologram without any further additions to this iconic statue of world cultural heritage. The composite digital file was finalized in preparation for its printing as a reflective digital hologram of 35x50 cm in dimension laminated on a hard glossy black plastic substrate. 

A stereoscopic visual impression of the composite digital file can be obtained by using the common red/blue auxiliary glasses for viewing the following anaglyph video preview.
