A propos de cet article

Gabor, Dennis. "Microscopy by Reconstructed Wavefronts" in "Proceedings of the Royal Society," A 197, London, 1949, published by Royal Society, London, 1949, iv, 576pp in the full volume, with the Gabor occupying pp 454-487. Finely and newly rebound in cloth-backed marbled boards, with new endpapers. Very Fine copy. [++] This is Gabor's full presentation of his effort in the creation of the hologram (following a preliminary report that was published in "Nature" 15 May 1948). It was also in this volume that Gabor uses the word "hologram" for the first time (according to the OED and DSB). The OED states that the word "hologram" is first used by Gabor in this paper on p 456 (bottom): "The name hologram is not unjustified, as the photograph contains the total information required for reconstructing the object, which can be two-dimensional or three-dimensional." However "hologram" appears just before that, on the same page, in a tech illustration, so I'm assuming that that is the first appearance of the word in print in this context. [++] Gabor had been searching for the trick to get around the barrier of the theoretical limit to resolution. During the Easter holiday in 1947, he was sitting on a bench at the local tennis club when an idea suddenly came to him: Why not take an electron picture distorted by lens imperfections and correct it by optical means? A few calculations convinced him he was right. Gabor was proposing a two-stage process. In the first stage an interference pattern produced by the interaction of electrons diffracted by the object and a separate but coherent reference beam of electrons would be photographically recorded on transparent film. Gabor argued that this interference pattern, or hologram, as he later called it, would carry the complete information needed to reconstruct an image of the object, using an optical system free from the limitations of electron optics. In the second stage, the hologram would be scaled up by a factor in the ratio of the wavelength of the light used in the reconstruction to the wavelength of the electron beam. The new hologram would then be illuminated with a light wave of the same aberration as the electron wave to, in theory, reveal an exact replica of the original object, magnified by the scaling factor."--Complete Dictionary of Scientific Biography, online. [++] Gabor received the Nobel Prize in physics in 1971 for this work, for his invention and development of the holographic method . "During the 19th century photographic methods were developed that resulted in two-dimensional images. In 1951 Dennis Gabor discovered a way of producing images with the illusion of depth. The method was based on interference interaction between light waves and coherence light waves aligned in phase with one another. Light falling on an object is captured on photographic film along with a reference beam that did not fall on the object. When only the reference beam falls on the developed film, the light is bent so that a reproduction with depth is produced."--Nobel Prize website.
