In the table top role playing game Traveller, ablative armor (referred to as Ablat) is an equipment option for characters to protect them from laser fire or other energy weapons. In the second edition of Traveller published by Game Designers's Workshop in 1981, Ablat is described as an "Ablative (vaporizing anti-laser) jacket" available for 75 ...
Infrared signature, as used by defense scientists and the military, is the appearance of objects to infrared sensors. [1] An infrared signature depends on many factors, including the shape and size of the object, [2] temperature, [3] and emissivity, reflection of external sources (earthshine, sunshine, skyshine) from the object's surface, [4] the background against which it is viewed [5] and ...
The scientists calculated that a huge reflector, made of metallic sodium and with an area of 9 square kilometres (900 ha; 3.5 sq mi), could produce enough focused heat to make an ocean boil or burn a city. [1] After being questioned by American officers, the Germans claimed that the sun gun could be completed within 50 or 100 years. [1] [2]
Cross-section of layers in space suit construction. An (Integrated) Thermal Micrometeoroid Garment (TMG or ITMG) is the outer layer of a space suit.The TMG has three functions: to insulate the suit occupant and prevent heat loss, to shield the occupant from harmful solar radiation, and to protect the astronaut from micrometeoroids and other orbital debris, which could puncture the suit and ...
A flare or decoy flare is an aerial infrared countermeasure used by an aircraft to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust ...
Inspired by the 1937 science fiction novel Star Maker by Olaf Stapledon, [4] the physicist and mathematician Freeman Dyson was the first to formalize the concept of what became known as the "Dyson sphere" in his 1960 Science paper "Search for Artificial Stellar Sources of Infra-Red Radiation".

Thermal weapon sights are often used by hunters to aid in the detection of game, such as feral hogs, coyotes, or rodents such as rats. The sight's ability to see unaided even in complete darkness allows the hunter to be undetected and aware of potential prey, facilitating a quick and precise takedown. [3]
