A German medical student, Heinrich Lamm produced a crude coherent bundle in the 1930s of perhaps 400 fibres. He was born July 27, 1965, in Bangor, the son of the late Galen S. Hopkins, and Pauline (Haskins) Hopkins of Bangor. Eventually so many are lost that the whole bundle must be replaced (at considerable expense).
Although there had been earlier attempts to produce a lens which could achieve continuously varying magnification without re-focusing, none of them could provide a good quality image throughout their zooming and aperture ranges. His Wave Theory of Aberrations, (published by Oxford University Press 1950), is central to all modern optical design and provides the mathematical analysis which enables the use of computers to create the wealth of high quality lenses available today. Whilst zoom lenses can never out-perform fixed focal lengths, the differences are no longer significant in most applications. I am so sorry for your loss, may God grant the necessary strength and comfort during these difficult days ahead. He proposed winding a single continuous length of fibre in a figure-of-eight around a pair of drums. This content is published for the entertainment of our users only. MTF is still used by optical designers as the principal criterion of image quality, although its measurement in production is less widespread than it used to be. His citation on receiving the Rumford Medal from the Royal Society in 1984 stated: "In recognition of his many contributions to the theory and design of optical instruments, especially of a wide variety of important new medical instruments which have made a major contribution to clinical diagnosis and surgery."[4].
Published in Idaho Press Tribune on Feb. 2, 2015. But Harold studied at the University of Besançon with Duffieux, who had already begun to lay the foundations of Fourier optics. July 12, 1926 - February 11, 2015 (88 years old) Woodland Hills, CA Services By Forest Lawn - Hollywood Hills Early life.
However, the Headmaster, recognising his exceptional gift for mathematics, directed him into science. To offer your sympathy during this difficult time, They also observed that light falling on one end was transmitted to the other. They were also incredibly hard to manufacture and assemble – and optically nearly useless. Send your deepest condolences with fresh flowers. In modern terminology, a bundle of say 50,000 fibres gives effectively only a 50,000 pixel image – in addition to which, the continued flexing in use, breaks fibres and so progressively loses pixels. Eventually a system for cladding fibres with a layer of glass of lower refractive index was developed (see Larry Curtis et al.) The application of computer design-programs based on his Wave Theory of Aberrations in conjunction with new types of glass, coatings and manufacturing techniques has transformed the performance of all types of lenses. Our condolences to the Hopkins family and friends. The 67-year-old was diagnosed several months ago, …
However, he took great delight in having conferred on him the Honorary Fellowships of all the medical Royal Colleges in Britain, together with the highest awards of many of the world's premier scientific bodies including (in 1973)[1] the Fellowship of the Royal Society itself. He began a research fellowship at Imperial College London in 1947, lecturing in optics.
They are arranged along a spiral path such that a laser can read them in sequence (in similar fashion to a stylus following the groove on a vinyl record). you can now have memorial trees planted in a National Forest in memory of your loved one.

As with the fibroscopes, a bundle of glass-fibers would relay the illumination from a powerful external source. Other innovations included the use of additional fibres to channel light to the objective end from a powerful external source (typically a xenon arc lamp) thereby achieving the high level of full spectrum illumination needed for detailed viewing and good quality colour photography.
The next twenty years saw him emerge as one of the foremost authorities in the field of optics. I'm sorry I never met him personally but his legacy through his wonderful family is well-evident. Coming from a poor and under-privileged background, he understood how essential equal opportunities and good education were if ordinary working class youngsters like himself were to prosper in society.
