Welcome to the archived version of the MIT Museum's online collections portal! This site was used to test features and content for the newly redesigned MIT Museum Collections site, which has now launched with over 106,000 objects. Please use the new MIT Museum Collections site for further research and discovery. Webmuseum.mit.edu remains online during the transition period but will not receive new updates or content.
Demonstration Apples
Major collection: Holography
Named collection: Holography Collection
Object type: hologram
Maker: Benton, Stephen A.; Jackson, Rosemary H.
Date made: 1978-1979
Materials: laser transmission; glass
Measurements: 13 1/2 in x 12 1/2 in x 1/4 in
Nomenclature: historical
Classification: holograms
Made to imitate Dr. Dennis Gabor's first experiments with mercury arc-lit transparencies; hologram is on a glass plate which is adhered to a slightly larger glass plate; the bottom inch of the larger plate overlaps the holographic plate, creating a lip that was used to place the hologram in a pedestal; 2 holes in the lip allowed the glass plate to be better secured in the pedestal; because of this set-up, large cracks appear in the lip (now held in place by tape), due to damage caused by Museum of Holography patrons. Please note that due to the unique challenges of holography as a medium, high-resolution digital images are not available for most items in the holography collection. Please contact us for more information on reproducing images of holograms.
