hologram
noun
ˈhä-
Did you know?
A hologram is a picture of a "whole" object, showing it in three dimensions. We've all seen cheap hologram images on credit cards and ID cards (where they help prevent copying). Far more impressive are large holograms that take the form of a ghostly 3-D moving figure that you can walk around to see from all angles. Holograms were invented in 1947 but only perfected after the invention of the laser in 1960. Today they're used in such technologies as compact-disc players and checkout scanners, and holograms can be created of the inside of live internal organs to permit doctors to examine the organs in great detail. And soon televisions with hologram technology may enable us to watch in "3-D".
