About this Item
Gabor, D.[ennis]; R.W. Berriman; and with R.H. Herz. Three significant papers, including Gabor's Nobel effort and announcement of the invention of HOLOGRAPHY. GABOR: "A New Microscopic Principle," pp .777-778. in C, 1948 (January-June), volume 16, lvi, 1028pp. The Gabor paper appears on pp 777-778 and offered in the full volume of 1028pp. Bound in stout cloth, the rear cloth board being somewhat faded. There are a few ownership rubber stamps on the interior, here and there, as well as a bookplate there are no exterior markings. A VERY GOOD copy. $500 "Gabor, assisted by Ivor Williams, began experiments at B.T.H. to establish the principle by using a purely optical model that is, using visible light instead of electrons with a mercury vapor lamp as a source of coherent light, to produce the interference photographs of simple two dimensional images. Five months later he was able to show his close confidant Lawrence Bragg his first successful wavefront reconstructions: hazy im ages of simple printed words used as objects. Even when Bragg fully understood the theory, he still stated that it was a miracle it should work. The first public indication of Gabor s success came with a preliminary note to "Nature", published on 15 May 1948. The following year he wrote a more complete theoretical treatment, for the "Proceedings of the Royal Society", in which he introduced the word hologram and indicated possible applications in light optics. Among these was the ability, using the same method, to record the data associated with 3-D objects in one interference photograph. Gabor s private correspondence was full of enthusiasm. To Max Born, he declared that his holographic reconstructions had made him happier than anything he had done in the last twenty years. And he told Arthur Koestler: I missed inventing the electron microscope when I was 27, and I have every intention to make a comeback, with a fresh start, at 48. --(Complete Dictionary of Scientific Biography online). Gabor received the Nobel Prize in 1971 "for his invention and development of the holographic method."--Nobel Prize committee. [++] Other papers in this volume include: BERRIMAN, R.W. "Electron Tracks in Photographic Emulsions," p. 432. Including an accompanying note on Berriman's paper: HERZ, R.H. "Electron Tracks in Photographic Emulsions," pp 928-929. In his abstract Herz notes "In a recent note, R. W. Berriman reported on a new photographic emulsion with which electron tracks can be recorded. Attempts have been made to relate energy and range of electron tracks in this type of photographic material, referred to as the NT2a plate. The electron tracks were obtained by exposing the plates to heavily filtered X-rays generated at increasing kilovoltages. The tracks were scanned under the microscope, and the number of grains of each track counted was plotted against the frequency of tracks. The curves so obtained show a shift of the maximum frequency towards greater numbers of grains with increasing kilo voltage. In a few cases where the tracks were at almost glancing angle to the plane of the plate, length measurements of the curved path of tracks were made."--Herz's paper, abstract.
