Group managing director for Telstra Enterprise and Government, David Thodey, said the live hologram symbolised what had become possible using the high data speed and capacity of Telstra's network. "It demonstrates what we at Telstra call 'Next Dimension Working' - a new and more productive way of working using technology to achieve better outcomes and an enhanced user experience from where ever you choose to be or whatever medium you choose to use." The Musion technology uses a single high definition camera to capture the image and a single HD projector to project it, onto a special foil. According to Musion, "All the images used on a Musion Eyeliner system appear as three-dimensional images, but are projected as two-dimensional images into a 3D stage set. It is the mind of the audience that creates the 3D illusion. This means that production costs are minimal, needing only the single camera lens single camera lens for filming and a single projector for the playback." The Eyeliner foil is the heart of the system, according to Musion which says its business is based around exploiting a number of patents that have been issued on producing Pepper's Ghost using the purpose designed foil rather than glass. The Eyeliner foil is "carefully prepared during manufacture and rolling so as to retain maximum transparency and strength when subject to extreme tension. The resulting smooth, blemish free surface betters that of a huge plate glass mirror, allowing the true reproduction of high definition video at such high quality that audiences viewing Eyeliner video images imagine them to be real." Pepper's Ghost was a theatrical technique invented by Professor John Henry Pepper and English engineer Henry Dircks in the 19th century to enable images of actors to appear and disappear on stage, in ghostly fashion. It relied on reflecting their image in a glass plate, and the need for very large plates to produce life size images limited its application. More recently the technique has been developed and exploited in Disney theme parks.
