Thales Optronics
Thales Optronics is a optronics manufacturer and a division of the French defence corporation Thales Group. It is headquartered in Paris. The company has three main subsidiaries: Thales Optronique SA in France, Thales Optronics Limited in the United Kingdom and Thales Optronics B.V in the Netherlands. History France United Kingdom Thales' optronics businesses in the UK trace their origins to Pilkington Optronics, which was formed by Pilkington plc in 1988 to take control of the company's optronics businesses: Pilkington PE located in North Wales (formed in 1966) and Barr and Stroud, which was based in Glasgow. Pilkington PE later became Thales Optics Ltd., which was divested from Thales in December 2005 as Qioptiq Ltd. In 1991 Thomson-CSF acquired 50% of Pilkington Optronics. In 1995 Pilkington Optronics acquired Thorn EMI Electro Optics which was renamed Pilkington Thorn Optronics. Three years later, Thomson-CSF purchased another 40% of Pilkington Optronics from Pilkington and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Division (business)
A division, sometimes called a business sector or business unit (segment), is one of the parts into which a business, organization or company is divided. Overview Divisions are distinct parts of a business. If these divisions are all part of the same company, then that company is legally responsible for all of the obligations and debts of the divisions. In the banking industry, an example would be East West Bancorp and its primary subsidiary, East West Bank. Legal responsibility Subsidiaries are separate, distinct legal entities for the purposes of tax A tax is a compulsory financial charge or some other type of levy imposed on a taxpayer (an individual or legal entity) by a governmental organization in order to fund government spending and various public expenditures (regional, local, or n ...ation, regulation and Legal liability, liability. For this reason, they differ from divisions, which are businesses fully integrated within the main company, and not legally ...

Joint Reconnaissance Pod
The Digital Joint Reconnaissance Pod (or DJRP) is a wide area tactical reconnaissance pod produced by Thales Optronics of Bury St Edmunds, England. It is the latest version of a pod produced for the UKMoD and the RAF Jaguar force, originally developed and produced by W. Vinten Ltd. The original designation of the pod was Jaguar Replacement Reconnaissance Pod (JRRP) and after successfully entering service in the 1990s it was subsequently redesignated DJRP, and fitted to a wide range of other aircraft. The current sensors are an 8042 EO sensor and a Super Vigil IR sensor; these feed digital data to two recording modules which provide storage. The pod functions are controlled by a reconnaissance management system, enabling both pre-planned and pilot-initiated events to be recorded. The sensors are configured to provide wide area coverage; the EO sensor records at both long and short range, providing a stand-off capability, while the IR sensor records a horizon-to-horizon image base ...

Optics Manufacturing Companies
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of optical instruments, instruments that use or Photodetector, detect it. Optics usually describes the behaviour of visible light, visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the Classical electromagnetism, classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of Ray (optics), rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles. More complex periscopes using prisms or advanced fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. Early examples Johannes Hevelius described an early ...

Optronics Mast
A photonics mast (or ''optronics mast''BBC News Scotland, A vision of evolving technologies' 30 August 2007, 13:06 GMT) is a sensor on a submarine which functions similarly to a periscope without requiring a periscope tube, thus freeing design space during construction and limiting risks of water leakage in the event of damage. A photonics mast replaces the mechanical, line-of-sight viewing system with digital equipment, similar to a digital camera array, and it has fewer locational and dimensional constraints than a traditional periscope. Unlike a periscope, it need not be located directly above its user, and it requires only a small pressure hull penetration for cabling. This allows the photonics mast to fit entirely within the sail of the submarine and means the control room need not be placed directly below the sail. A photonics mast operates by rising above the water in a manner similar to a telescoping antenna and provides information through an array of sensors, such as ...

Laser Countermeasures
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 light wit ...

Laser Warning Receiver
A laser warning receiver is a type of warning system used as a passive military defence. It detects, analyzes, and locates directions of laser emissionsPDF version4.53 MB) from laser guidance systems and laser rangefinders. Then it alerts the crew and can start various countermeasures, like smoke screen, aerosol screen (e.g. Shtora), active laser self-defence weapon with laser dazzler (LSDW, used on the Chinese Type 99 main battle tank), laser jammer, etc. Detectors used in LWR are usually based on a semiconductor photodetector array, which is typically cryogenically or thermal-electric cooled. Sometimes avalanche photodiodes (APD), photoconductivity, photoelectromagnetic, or photodiffusion devices are used even without cooling. Some devices detect only the main beam of foreign lasers while others detect even scattered rays.

IRST
An infrared search and track (IRST) system (sometimes known as infrared sighting and tracking) is a method for detecting and tracking objects which give off infrared radiation, such as the infrared signatures of jet aircraft and helicopters. IRST is a generalized case of forward looking infrared (FLIR), i.e. from forward-looking to all-round situation awareness. Such systems are passive ( thermographic camera), meaning they do not give out any radiation of their own, unlike radar. This gives them the advantage that they are difficult to detect. However, because the atmosphere attenuates infrared to some extent (although not as much as visible light) and because adverse weather can attenuate it also (again, not as badly as visible systems), the range compared to a radar is limited. Within range, angular resolution is better than radar due to the shorter wavelength. History Early systems The first use of an IRST system appears to be the F-101 Voodoo, F-102 Delta Dagger and ...

Eurofighter Typhoon
The Eurofighter Typhoon is a European multinational twin-engine, canard delta wing, multirole fighter. The Typhoon was designed originally as an air-superiority fighter and is manufactured by a consortium of Airbus, BAE Systems and Leonardo that conducts the majority of the project through a joint holding company, Eurofighter Jagdflugzeug GmbH. The NATO Eurofighter and Tornado Management Agency, representing the UK, Germany, Italy and Spain, manages the project and is the prime customer. The aircraft's development effectively began in 1983 with the Future European Fighter Aircraft programme, a multinational collaboration among the UK, Germany, France, Italy and Spain. Previously, Germany, Italy and the UK had jointly developed and deployed the Panavia Tornado combat aircraft and desired to collaborate on a new project, with additional participating EU nations. However disagreements over design authority and operational requirements led France to leave the consortium to deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
