Military Camouflage
Military camouflage is the use of camouflage by an Military, armed force to protect personnel and equipment from observation by enemy forces. In practice, this means applying colour and materials to military equipment of all kinds, including vehicles, ships, aircraft, gun positions and battledress, either to conceal it from observation (crypsis), or to make it appear as something else (mimicry). The French slang word ''wikt:camouflage, camouflage'' came into common English usage during World War I when the concept of visual deception developed into an essential part of modern military tactics. In that war, long-range artillery and observation from the air combined to expand the field of fire, and camouflage was widely used to decrease the danger of being targeted or enable surprise. As such, military camouflage is a form of military deception in addition to cultural functions such as political identification. Camouflage was first practiced in simple form in the mid 18th centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a Raster graphics, raster image, or the smallest addressable element in a dot matrix display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a Sampling (signal processing), sample of an original image; more samples typically provide more accurate representations of the original. The Intensity (physics), intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as RGB color model, red, green, and blue, or CMYK color model, cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''wikt:sensel, sensel'' is sometimes used), while in yet ...

CADPAT
The Canadian Disruptive Pattern (CADPAT; ) is the computer-generated digital camouflage pattern developed for use by the Canadian Armed Forces. Four operational variations of CADPAT have been used by the Canadian Armed Forces: a temperate woodland pattern, an arid regions pattern, a winter operations pattern, and a multi-terrain pattern. CADPAT was the first digital camouflage pattern to be used operationally, having been issued in 1997 with the Canadian Armed Forces. The pattern became fully standardized within the Canadian Armed Forces by 2002, having completely replaced the olive-drab operational uniforms formerly used by Regular Force units. Development of the multi-terrain CADPAT variant began in 2019 and is being issued to replace temperate woodland and arid CADPAT variants. History Canada's desire for a new soldier system dated back to November 1988 and closely followed efforts in many NATO countries. The first research effort, called Integrated Protective Clothing and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dazzle Camouflage
Dazzle camouflage, also known as razzle dazzle (in the U.S.) or dazzle painting, is a type of ship camouflage that was used extensively in World War I, and to a lesser extent in World War II and afterwards. Credited to the British marine artist Norman Wilkinson, though with a rejected prior claim by the zoologist John Graham Kerr, it consisted of complex patterns of geometric shapes in contrasting colours interrupting and intersecting each other. Unlike other forms of camouflage, the intention of dazzle is not to conceal but to make it difficult to estimate a target's range, speed, and heading. Norman Wilkinson explained in 1919 that he had intended dazzle primarily to mislead the enemy about a ship's course and so cause them to take up a poor firing position. Dazzle was adopted by the Admiralty in the UK, and then by the United States Navy. Each ship's dazzle pattern was unique to avoid making classes of ships instantly recognisable to the enemy. The result was that a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Countershading
Countershading, or Thayer's law, is a method of camouflage in which animal coloration, an animal's coloration is darker on the top or upper side and lighter on the underside of the body. This pattern is found in many species of mammals, reptiles, birds, fish, and insects, both in predators and in prey. When light falls from above on a uniformly coloured three-dimensional object such as a sphere, it makes the upper side appear lighter and the underside darker, grading from one to the other. This pattern of light and shade makes the object appear solid, and therefore easier to detect. The classical form of countershading, discovered in 1909 by the artist Abbott Handerson Thayer, works by counterbalancing the effects of self-shadowing, again typically with grading from dark to light. In theory this could be useful for military camouflage, but in practice it has rarely been applied, despite the best efforts of Thayer and, later, in the Second World War, of the zoologist Hugh Cott. ...

A-7D Corsairs 354th TFW At Korat 1972
The LTV A-7 Corsair II is an American carrier-capable subsonic light attack aircraft designed and manufactured by Ling-Temco-Vought (LTV). The A-7 was developed during the early 1960s as replacement for the Douglas A-4 Skyhawk. Its design was derived from the Vought F-8 Crusader; in comparison with the F-8, the A-7 is both smaller and restricted to subsonic speeds, its airframe being simpler and cheaper to produce. Following a competitive bid by Vought in response to the United States Navy's (USN) ''VAL'' (Heavier-than-air, Attack, Light) requirement, an initial contract for the type was issued on 8 February 1964. Development was rapid, first flying on 26 September 1965 and entering squadron service with the USN on 1 February 1967; by the end of that year, A-7s were being deployed overseas for the Vietnam War. Initially adopted by USN, the A-7 proved attractive to other services, soon being adopted by the United States Air Force (USAF) and the Air National Guard (ANG) to replac ...

Ian Hamilton Finlay
Ian Hamilton Finlay (28 October 1925 – 27 March 2006) was a Scottish poet, writer, artist and gardener. Life Finlay was born in Nassau, Bahamas, to James Hamilton Finlay and his wife, Annie Pettigrew, both of Scots descent. He was educated at Dollar Academy in Clackmannanshire and later at Glasgow School of Art. At the age of 13, with the outbreak of the Second World War, he was Evacuations of civilians in Britain during World War II, evacuated to family in the countryside (firstly to Gartmore and then to Kirkudbright). In 1942, he joined the British Army. Finlay was married twice and had two children, Alec Finlay, Alec and Ailie. Throughout his life, he suffered severely from agoraphobia. He died in Edinburgh in 2006. He is buried alone in Abercorn Churchyard in West Lothian, Scotland. The grave lies in the extreme south-east corner of the churchyard.

Andy Warhol
Andy Warhol (;''Random House Webster's Unabridged Dictionary''"Warhol" born Andrew Warhola Jr.; August 6, 1928 – February 22, 1987) was an American visual artist, film director and producer. A leading figure in the pop art movement, Warhol is considered one of the most important American artists of the second half of the 20th century. His works explore the relationship between artistic expression, advertising, and celebrity culture that flourished by the 1960s, and span a variety of media, including painting, sculpture, photography, and filmmaking. Some of his best-known works include the silkscreen paintings ''Campbell's Soup Cans'' (1962) and '' Marilyn Diptych'' (1962), the experimental film '' Chelsea Girls'' (1966), the multimedia events known as the '' Exploding Plastic Inevitable'' (1966–67), and the erotic film '' Blue Movie'' (1969) that started the " Golden Age of Porn". Born and raised in Pittsburgh in a family of Rusyn immigrants, Warhol initially pursued ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab AB
Saab AB (originally , , acronym SAAB), with subsidiaries collectively known as the Saab Group (), is a Swedish aerospace and defense company, defence company primarily operating from Sweden. The company is headquartered in Stockholm, but its development and manufacturing operations are undertaken in Linköping. The company was formally founded by AB Bofors in 1937, by reforming the aero engine division of company NOHAB (founded in 1930), located in Trollhättan, into a proper aircraft manufacturer. It would soon merge with aircraft manufacturer AB Svenska Järnvägsverkstädernas Aeroplanavdelning, ASJA (founded in 1931), located in Linköping, in 1940, which had it own design bureau and is considered the spiritual predecessor to today's Saab AB. This formed the SAAB-Concern (business), concern, with the factory in Trollhättan becoming ''SAAB/T'' and the factory in Linköping (previously ASJA) becoming ''SAAB/L'' and design headquarters. From 1947, Saab started producing autom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermography
Infrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals becom ...

Ultraviolet
Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs, Cherenkov radiation, and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. The photons of ultraviolet have greater energy than those of visible light, from about 3.1 to 12 electron volts, around the minimum energy required to ionize atoms. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack sufficient energy, it can induce chemical reactions and cause many substances to glow or fluoresce. Many practical applications, including chemical and biological effects, are derived from the way that UV radiation can interact with organic molecules. The ...

Short-wave Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
