An example of a hologram produced in Canada. Starlight Holographic Inc. of Kanata, Ontario was a manufacturer of holograms in the early 1990's which found practical applications for holography. This hologram was one of 75 copies made from the original master. Starlight also designed & co-ordinated production of A Clear Day Hologram for Northern Telecom, commissioned to mark the company's phase-out of chlorofluorocarbons,. NT bought 70 copies for its major company locations (Ref. 1).

Fonction

A medium which presents a three dimensional image, in this case a map of the earth.

Technique

An example of a large reflection type hologram. This hologram was assembled from 300 images of the Earth from space such that it appears cloudless. One can view the image from 3 angles and thus get different perspectives. In this hologram, the Earth looks about the size of a large beachball and can be viewed from three perspectives. It was assembled from 300 detailed photographs, each a slightly different angle of view as constructed from satellite data. The data were collected by U.S. photographer Thomas Van Sant for his widely published work The Earth from Space. It took five days on a high-powered computer to render the data into 300 images. At Applied Holographics, a Los Angeles lab, the computer images were then photographed, one frame apiece. Laser light was then used to expose the film on a sensitive holographic recording emulsion. Multiple exposures created a sense of depth. The frames were arranged in three groups of 100, to offer three different views of the globe. This master hologram was then used to produce 75 copies, individually laminated to half-centimetre thick plates of mirrored plexigiass. When light is shone on these holograrns, a colored, 3-D image of the world appears to. float in space on the far side (Ref. 1).
