... Photometric image are characterized by quantitative relations between the detected intensity and the light signal emitted by the measured object. Therefore, they are important for scientific applications. The image sampled with slow scan cameras consist of high dynamic and linearity. Furthermore, du ...

Ab initio calculations of optical properties of silver clusters: Cross

... Since one of the aims here is to compare the applicabilities of the two different approaches, the results presented in this work do not include any shift except for ∼0.3 eV blue-shift to the WIEN2k data to align with the SIESTA results for easier comparison. Our calculations of the extinction coeffi ...

Harold Hopkins (physicist)

Harold Horace Hopkins FRS (1918–1994) was a renowned British physicist. 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. In addition to his theoretical work, his many inventions are in daily use throughout the world. These include zoom lenses, coherent fibre-optics and more recently the rod-lens endoscopes which 'opened the door' to modern key-hole surgery. He was the recipient of many of the world's most prestigious awards and was twice nominated for a Nobel Prize. 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.""
