In a traditional hologram, laser light is shined on a 2-dimensional image and a ghostly 3D object appears. In the new holography, the 2-dimensional "molecular holograms" are illuminated not by laser light but by the electrons that are already in the copper in great abundance. The resulting "electronic object" can be read with the scanning tunneling microscope.
So there is a different process involved.--Salix (talk): 21:17, 12 March 2012 (UTC)
