Infrared thermometer. An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns ...
Infrared thermography ( IRT ), thermal video and/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 ...
Directed-energy weapon. Police car equipped with an LRAD -500X sonic weapon (Warsaw, Poland, 2011). A directed-energy weapon ( DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams.
Infrared (IR) thermography [2] is an analysis technique based on the detection of radiation in the IR part of the electromagnetic spectrum. According to the black body radiation law, all objects with temperature greater than absolute zero emit IR radiation. The device detecting and composing a 2D image of the IR radiation is generally called an ...
Infrared. A false-color image of two people taken in long-wavelength infrared (body-temperature thermal) radiation. This pseudocolor infrared space telescope image has blue, green, and red corresponding to wavelengths of 3.4, 4.6, and 12 μm, respectively. Infrared ( IR; sometimes called infrared light) is electromagnetic radiation (EMR) with ...
Thermal weapon sight. A Thermal Weapon Sight. Produced by Meprolight, Mepro NYX. A thermographic weapon sight, thermal imagery scope or thermal weapon sight is a sighting device combining a compact thermographic camera and an aiming reticle. [ 1] They can be mounted on a variety of small arms as well as some heavier weapons.
A thermometer is a device that measures temperature (the degree of hotness or coldness of an object) or temperature gradient (the rates of change of temperature in space). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in ...
Inset shows false color infrared thermograph of a roof on a sunny day; the white surfaces (colored blue in the thermograph) have been coated with an elastomer to reduce solar loading and have a surface temperature of approximately 60 °F (16 °C); the gray surfaces (colored red/white in the thermogram) are a standard asphalt (bitumen) coating and have a surface temperature of approximately 160 ...
