Three-dimensional images formed by exposing a negative image with monochromatic radiation from a laser while it is positioned in a second laser beam. The direct beam and the image scattered beam combine to form an interference pattern that is viewed as a three-dimensional image. The technique for making holograms was invented in 1947 by Dennis Gabor of Hungary, but was not widely used until after the laser was invented in 1960. Salvador Dali used holography to make works of art.

Door holografie verkregen beeld interferentiepatroon. (nl)
Dreidimensionales Bild, das entsteht, wenn man ein Negativ den monochromatischen Strahlen eines Lasers aussetzt, während es in einen zweiten Laser-Strahl positioniert wird. Der direkte Strahl und der durch das Bild zerstreute Strahl formen zusammen ein Interferenz-Muster, das als dreidimensionales Bild gesehen wird. Die Technik zur Herstellung von Hologrammen ist 1947 von Dennis Gabor in Ungarn entwickelt worden, aber es war nicht weit verbreitet vor der Erfindung des Lasers 1960. Salvador Dali verwendete Holographie für seine Kunstwerke. (de)
