What is infrared thermography?

Infrared thermography is a procedure for creating images using infrared (IR) radiation instead of light. IR is invisible to the naked eye, but is emitted or reflected by any object or creature that gives heat. Infrared thermography, also known simply as thermography, creates an image based on thermal samples of the area. It has a number of technical and scientific applications, from military supervision to astronomy. The thermography image is called a thermogram.

Infrared radiation is part of the electromagnetic spectrum, a wide range of harmless radiation, which includes visible light, radio waves and microwaves. The wavelength of the radiation determines its nature and position on the electromagnetic spectrum. Although the human eye can only detect the narrow range of this radiation, the rest can find out different technological devices. The wavelength of the infrared radiation places it between microwaves and red light, just outside the visible spectrum.ir of radiation, which is close to the visible range, can be attachedtit with special cameras for IR photography; Infrared thermography can capture IR radiation, which is closer to the microwave, known as far infrared.

IR radiation of the building is closely associated with its temperature. As a result, infrared thermography can detect fine variations of heat emitted by an object, creation or person. As all objects emit a certain amount of heat, thermography allows observing the environment in its completeness, even in the complete absence of light. For example, the thermogram of the house can show exteriors outlined blue, but internal sources of heat and energy, including people, such as red objects. These properties of thermography have multiple applications in a wide range of fields and professions.

For example, in medicine, infrared thermography can help early diagnosis of the disease by increased heat levels caused by fever. Military Personnel uses thermography for supervision and operation ifwould be ordinary light sources dangerous. Meteorologists can detect temperature changes that indicate the storms and other rapidly changing weather patterns. Building thermograms can detect "hot spots", allowing technicians to find problem areas in ventilation or electrical system before causing failure. Even archaeologists use thermography to find buried structures that absorb or reflect heat differently than the surrounding terrain.

Astronomers have used infrared radiation for decades because they can detect heavenly bodies outside the range of common telescopes. The use of infrared thermography for astronomy was initially limited because the atmosphere of the Earth absorbs and diverts so much IR radiation. However, the surrounding cosmic telescopes can use thermographic equipment without such restrictions. This equipment must be cooled to prevent external data sources of data distorting. Thermograms were used to observe distant planetary bodies and infant stars that have not yet begunIf you emit a visible light.
