Nicholas J. Phillips
Nicholas (Nick) John Phillips (26 September 1933 – 23 May 2009) was an English physicist, notable for the development of photochemical processing techniques for the colour hologram. Holograms typically used to have low signal-to-noise ratios, and Phillips is credited as the pioneer of silver halide holographic processing techniques for producing high-quality reflection holograms. Career Phillips graduated with a BSc degree in physics from Imperial College, London. He was a senior researcher at the Atomic Weapons Research Establishment (AWRE), Aldermaston, from 1959 to 1962. He was a research scientist at the Sperry Rand Research Centre, Sudbury, Massachusetts, United States, from 1962 to 1963. He was a theoretical physicist at English Electric, Whetstone, Leicester, UK, from 1963–1965. From 1965 to 1993 he was appointed at Loughborough University, where he rose to Professor of Applied Optics. In October 1993, he was appointed as Professor of Imaging Science at De Montfort ...

Holographic
Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating real three-dimensional images, but it also has a wide range of other Holography#Applications, applications. In principle, it is possible to make a hologram for any type of Holography#Non-optical holography, wave. A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium. When only the second wavefront illuminates the interference pattern, it is diffracted to recreate the original wavefront. Holograms can also be Computer-generated holography, computer-generated by modelling the two wavefronts and adding them together digitally. The resulting digital image is then printed onto a suitable mask or film and illuminated by a suitable source to reconstruct the wavefront of interest. Overview and ...

Silver Halide
A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver (Ag) and one of the halogens. In particular, bromine (Br), chlorine (Cl), iodine (I) and fluorine (F) may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and three forms of silver fluoride, respectively. As a group, they are often referred to as the silver halides, and are often given the pseudo-chemical notation AgX. Although most silver halides involve silver atoms with oxidation states of +1 (Ag+), silver halides in which the silver atoms have oxidation states of +2 (Ag2+) are known, of which silver(II) fluoride is the only known stable one. Silver halides are light-sensitive chemicals, and are commonly used in photographic film and paper. Applications Light sensitivity Silver halides are used in photographic film and photographic paper, including graphic art film and paper, where silver halide crystals in g ...

Bruce R
The English language name Bruce arrived in Scotland with the Normans, from the place name Brix, Manche in Normandy, France, meaning "the willowlands". Initially promulgated via the descendants of king Robert the Bruce (1274−1329), it has been a Scottish surname since medieval times; it is now a common given name. The variant ''Lebrix'' and ''Le Brix'' are French variations of the surname.

Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of ligh ...

Royal Academy
The Royal Academy of Arts (RA) is an art institution based in Burlington House on Piccadilly in London. Founded in 1768, it has a unique position as an independent, privately funded institution led by eminent artists and architects. Its purpose is to promote the creation, enjoyment and appreciation of the visual arts through exhibitions, education and debate. History The origin of the Royal Academy of Arts lies in an attempt in 1755 by members of the Society for the Encouragement of Arts, Manufactures and Commerce, principally the sculptor Henry Cheere, to found an autonomous academy of arts. Prior to this a number of artists were members of the Society for the Encouragement of Arts, Manufactures and Commerce, including Cheere and William Hogarth, or were involved in small-scale private art academies, such as the St Martin's Lane Academy. Although Cheere's attempt failed, the eventual charter, called an 'Instrument', used to establish the Royal Academy of Arts over a decad ...

The Who
The Who are an English rock band formed in London in 1964. Their classic lineup consisted of lead singer Roger Daltrey, guitarist and singer Pete Townshend, bass guitarist and singer John Entwistle, and drummer Keith Moon. They are considered one of the most influential rock bands of the 20th century, and have sold over 100 million records worldwide. Their contributions to rock music include the development of the Marshall Stack, large PA systems, the use of the synthesizer, Entwistle and Moon's influential playing styles, Townshend's feedback and power chord guitar technique, and the development of the rock opera. They are cited as an influence by many hard rock, punk rock, power pop and mod bands, and their songs are still regularly played. The Who were inducted into the Rock and Roll Hall of Fame in 1990. The Who developed from an earlier group, the Detours, and established themselves as part of the pop art and mod movements, featuring auto-destructive art by d ...

Whetstone, Leicestershire
Whetstone is a village and civil parish in the Blaby district of Leicestershire, England and largely acts as a commuter village for Leicester, five miles to the north. The population at the 2011 census was 6,556. It is part of the Leicester Urban Area. The village is bounded on the east by the A426 (on the other side of which is Blaby village), to the north by the railway line from Birmingham to Leicester, and to the west by the M1. It is well connected to Leicester City centre, with a very frequent direct bus service. From 1899 to 1963 the village was served by Whetstone railway station. Whetstone was the site of Frank Whittle's factory, where jet engines were developed. Babcock Services, ITP Engines Ltd and Converteam now occupy much of the site. Smaller companies rent space, mainly for storing commercial vehicles. Until 2002 the site sounded an Air Raid Siren at 8am every Wednesday. The site of the Whittle factory became the English Electric Company (later GEC). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
