Holograms habe been discribed as "frozen slices of light" capable of producing three-dimensional imgages. The creation of holograms numerically by a computer opens the posibility of obtaining 3-D pictures of "objects" that exist only in concept, rather than in a physical reality, according to IBM. For example, using the computer technique, an engineer may obtain a 3-D picture of a bridge design while it is still on the drawing board. Also, by converting otherwise invisible waves - such as radar and ultrasonics - to digital holograms, scientists may be able to obtain 3-D pictures of the moon, planets and internal body organs. In a paper by James A. Jordan, Jr., Peter Hirsch and Louis B. Lesem, shown left to right at the IBM Scientific Center, Houston, Texas, the researchers discrible how they have instructed a computer, (in background), to calculate the interference patterns that would be created if light waves actually were reflected from a real object. Neither the real object nor actual light waves are required to produce the digital holograms. Rather, the computer uses mathematical descriptions of the objecet and the holographic process. The plotting apparatus shown in the foreground converts the computer hologram to a printed form which may be photographed to produce a more conventional optical hologram. When viewed under laser light, the film displays the reconstructed image of the object. (A computer hologram of the Greek letter lambda appears on the plotter in this photo). The paper was presented at the International Symposium on Modern Optics, organized by the Polytechnic Institute of Brooklyn and held at the Waldorf-Astoria Hotel March 22-24 1967. Anmerkung: Die Holografie ist ein fotografisches Verfahren zur Aufzeichnung von (u.A.) Bildinformation eines abgelichteten Objekts inklusive seiner räumlichen (dreidimensionalen) Information. Mittels Laserlicht wird dabei das gesamte Wellenfeld auf eine geeignete Fotoplatte abgebildet. Da das direkte Laserlicht mit dem vom Objekt reflektierten Laserlicht (auch) auf der Bildplatte überlagert wird und interferiert, enthält die holografische Bildplatte Informationen über Amplitude und Phase des vom Objekt kommenden Wellenfeldes und damit die Rauminformation über das Objekt.
