holographs (photographs)
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.
Kolmemõõtmelised kujutised, mis on saadud säritades laserkiire sisse asetatud negatiivkujutist ühevärvilise laserkiirgusega. Otsene kiir ja kujutisel hajutatud kiir ühinevad interferentsimustriks, mis on vaadeldav kolmemõõtmelise kujutisena. Hologrammide valmistamise tehnika leiutati 1947. aastal ungarlase Dennis Gabor´i poolt, kuid see seda ei kasutatud laiemalt enne laseri leiutamist 1960. aastal. Salvador Dali kasutas holograafiat kunstiteoste valmistamiseks.
