How Do Holograms Work? (Part 1 of 3)
Science-fiction is littered with holograms, and they’ve become a staple of anything set in the future. But, they’ve been around longer than you think.

The History of Holography
“Hungarian scientist Denis Gabor invents holography (for which he is awarded the Nobel Prize for Physics in 1971); he made two-dimensional (flat image) holograms with a mercury arc lamp using exposures of many hours.”
Lippmann’s and Gabor’s Revolutionary Approach to Imaging
/
“Both methods had the same goal of carrying image reproduction further in a way that was quite different from other earlier attempts made for the same purpose. To achieve this, Lippmann and Gabor chose a revolutionary approach to fundamental physics instead of following an evolutionary progress in engineering.”
How Holograms Work
“The microscopic interference fringes on a hologram don't mean much to the human eye. In fact, since the overlapping fringes are both dark and microscopic, all you're likely to see if you look at the developed film of a transmission hologram is a dark square. But that changes when monochrome light passes through it.”
