What is Infrared Thermography?
Here at Digital Thermal Power we believe in how important is emitted radiation to understand our environment, and yet we have successfully launched three different application since our launch in less than six months since. It is a non-destructive or non-invasive inspection and measurement technique to which temperature on any surface is measured.
The inspection process takes places uses infrared devices that measures emitted infrared radiation from the instrument or any surface. It is used to detect thermal anomalies that may indicate potential damage to a structure in place, and it shall identify a vast range of problem in the building. Accurate diagnosis of a thermography inspection from a trained professional should identify energy loss, airflow, air leakage, moisture levels, insulation defects and the building envelope, electrical connection anomalies.

What is Infrared Thermography? Definition of Infrared Thermography Infrared thermography is equipment or method, which detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution. To be accurate, the equipment and the method should be called differently, the equipment to be called as infrared thermograph and the method to be called as infrared thermography.
Recently, however, more and more public literatures show tendency not to pay attention to such appellative. We call our equipment as infrared thermography considering such generalization of the terminology. Characteristics of Infrared Thermography equipment It captures as a temperature distribution on a surface,and it can display as a visible information.
Temperature can be measured from a distance without contacting an object.1506g new software december 2019
Temperature can be measured in real time. Merits of Infrared Thermography equipment Relative comparison of distribution of surface temperature can be made over a wide area.
Temperature can be measured easily for a moving object or an object which is dangerous to get close to. Temperature of small object can be measured without confusing the temperature. Temperature of food, medicine or chemicals can be measured in a sanitary fashion. Temperature of an object with drastic temperature change or a phenomenon during a short period of time can be measured.
Infrared thermography is equipment or method, which detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution. It captures as a temperature distribution on a surface,and it can display as a visible information. Relative comparison of distribution of surface temperature can be made over a wide area.
It should be noted, however, that it may be affected by the reflection from the vicinity. However, you may be able to estimate the rear side if there is a temperature distribution appearing on the surface due to the difference in heat conductivity. Discovery of infrared It was discovered by a British astronomer, Herschel, in When dispersing sunlight using a prism, Herschel accidentally found that there was an invisible light on the outside of red light when increases the temperature of an object.
It is an electromagnetic wave Wavelength is 0. It is invisible since its wavelength is longer than visible light. It has nothing to do with brightness or darkness of visible light It is emitted naturally from any object of which temperature is absolute zero 0K or higher. Therefore, it can be applied to any field It has a characteristic of heating an object.
Therefore, it is sometimes called "heat wave". There is a correlation between infrared energy and temperature of an object. Therefore, it can be used to measure the temperature of an object. Emission: A type of heat transfer where the heat is transferred directly from the surface of an object as an infrared energy.
Convection: A type of heat transfer where the heat is transferred by the heated part of gas or liquid moving upward. Conduction: A type of heat transfer mainly through a solid object. An object which absorbs infrared well emits infrared well. Arrangement of detector and image data of infrared thermography.
Temperature distribution image data of infrared thermography consists of matrix of pixels number of detector: for example, horizontal X vertical pixels as shown in the figure above.A thermographic camera also called an infrared camera or thermal imaging camera or thermal imager is a device that creates an image using infrared radiationsimilar to a common camera that forms an image using visible light.
The art of capturing and analyzing the data they provide is called thermography. Infrared was discovered in by Sir William Herschel as a form of radiation beyond red light. These "infrared rays" infra is the Latin prefix for "below" were used mainly for thermal measurement. The development of detectors was mainly focused on the use of thermometers and bolometers until World War I.
A significant step in the development of detectors occurred inwhen Leopoldo Nobiliusing the Seebeck effectcreated the first known thermocouplefabricating an improved thermometer, a crude thermopile. He described this instrument to Macedonio Melloni. Initially, they jointly developed a greatly improved instrument. Subsequently, Melloni worked alone, developing an instrument in a multielement thermopile that could detect a person 10 metres away.
Byit had the capability to detect radiation from a cow from metres away, and was sensitive to differences in temperature of one hundred thousandths of a degree Celsius.
The first advanced application of IR technology in the civil section may have been a device to detect the presence of icebergs and steamships using a mirror and thermopile, patented in Barker's proposal to use the IR system to detect forest fires in This was created by the US military and Texas Instruments in  [ failed verification ] and took one hour to produce a single image.
While several approaches were investigated to improve the speed and accuracy of the technology, one of the most crucial factors dealt with scanning an image, which the AGA company was able to commercialize using a cooled photoconductor. The first infrared linescan system was the British Yellow Duckling of the mids. Although unsuccessful in its intended application of submarine tracking by wake detectionit was applied to land-based surveillance and became the foundation of military IR linescan.
This work was further developed at the Royal Signals and Radar Establishment in the UK when they discovered that mercury cadmium telluride was a photoconductor that required much less cooling. Honeywell in the United States also developed arrays of detectors which could cool at a lower temperature, [ further explanation needed ] but they scanned mechanically.
This method had several disadvantages which could be overcome using an electronic scanning system. In Michael Francis Tompsett at English Electric Valve Company in the UK patented a camera which scanned pyro-electronically and which reached a high level of performance after several other breakthroughs throughout the s. One of the most important areas of development for security systems was for the ability to intelligently evaluate a signal, as well as warning of a threat's presence.
These are sensors that could integrate sensing, signal extraction, processing, and comprehension. One, similar to what is called a " vision chip " when used in the visible range, allow for preprocessing using Smart Sensing techniques due to the increase in growth of integrated microcircuitry. Towards the end of the s, the use of infrared was moving towards civil use. There was a dramatic lowering of costs for uncooled arrays, which along with the large increase in developments lead to a dual way use market between civil and military.
Infrared energy is just one part of the electromagnetic spectrumwhich encompasses radiation from gamma raysx-raysultra violeta thin region of visible lightinfraredterahertz wavesmicrowavesand radio waves. These are all related and differentiated in the length of their wave wavelength. All objects emit a certain amount of black body radiation as a function of their temperature. Generally speaking, the higher an object's temperature, the more infrared radiation is emitted as black-body radiation.
A special camera can detect this radiation in a way similar to the way an ordinary camera detects visible light.The intensity of the infrared radiation emitted by objects is mainly a function of their temperature.
In infrared thermography, this feature is used for multiple purposes: as a health indicator in medical applications, as a sign of malfunction in mechanical and electrical maintenance or as an indicator of heat loss in buildings. This paper presents a review of infrared thermography especially focused on two applications: temperature measurement and non-destructive testing, two of the main fields where infrared thermography-based sensors are used.
A general introduction to infrared thermography and the common procedures for temperature measurement and non-destructive testing are presented. Furthermore, developments in these fields and recent advances are reviewed. Infrared thermography IRT is a science dedicated to the acquisition and processing of thermal information from non-contact measurement devices [ 1 ]. It is based on infrared radiation below reda form of electromagnetic radiation with longer wavelengths than those of visible light.
Any object at a temperature above absolute zero i. The human eye cannot see this type of radiation. Thus, infrared measuring devices are required to acquire and process this information [ 3 ].
Infrared measuring devices acquire infrared radiation emitted by an object and transform it into an electronic signal [ 4 ].
The most basic infrared device is a pyrometer, which produces a single output using a single sensor. Most advanced devices include an array of sensors to produce a detailed infrared image of the scene.
The difference between a visible image and an infrared image is that the visible image is a representation of the reflected light on the scene, whereas in the infrared image, the scene is the source and can be observed by an infrared camera without light.
Images acquired using infrared cameras are converted into visible images by assigning a color to each infrared energy level. The result is a false-color image called a thermogram [ 5 ]. IRT has many advantages over other technologies [ 6 ]. In general, the main advantages of IRT are the following:. IRT is a non-contact technology: the devices used are not in contact with the source of heat, i.
In this way, the temperature of extremely hot objects or dangerous products, such as acids, can be measured safely, keeping the user out of danger. IRT provides two-dimensional thermal images, which make a comparison between areas of the target possible. IRT is in real time, which enables not only high-speed scanning of stationary targets, but also acquisition from fast-moving targets and from fast-changing thermal patterns.
IRT has none of the harmful radiation effects of technologies, such as X-ray imaging. Thus, it is suitable for prolonged and repeated use.
IRT is a non-invasive technique. Thus, it does not intrude upon or affect the target in any way.
CHANGING THE WAY YOU READ YOUR BODY
IRT provides particular advantages in the medical and veterinary field, as it provides accurate readings without invasive procedures. The fact that IRT is a non-contact technique is very important in this field, because this means that it is a painless procedure.
Moreover, as the instrument is non-contact, it does not affect the result of the measurement and can be carried out remotely. Other alternatives can be painful, and when the sensor is in contact with the animal, it can affect the measurement.
Therefore, IRT is very effective, not only for measuring the temperature of the animal, but other variables, such as stress [ 7 ].Infrared thermography IRTthermal imagingand thermal video are examples of infrared imaging science. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation lawthermography 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 become easily visible against the environment, day or night.
As a result, thermography is particularly useful to the military and other users of surveillance cameras. Some physiological changes in human beings and other warm-blooded animals can also be monitored with thermal imaging during clinical diagnostics.
Thermography is used in allergy detection and veterinary medicine.
Some alternative medicine practitioners promote its use for breast screeningdespite the FDA warning that "those who opt for this method instead of mammography may miss the chance to detect cancer at its earliest stage". Thermography has a long history, although its use has increased dramatically with the commercial and industrial applications of the past fifty years.
Firefighters use thermography to see through smoketo find persons, and to localize the base of a fire. Maintenance technicians use thermography to locate overheating joints and sections of power lineswhich are a sign of impending failure. Building construction technicians can see thermal signatures that indicate heat leaks in faulty thermal insulation and can use the results to improve the efficiency of heating and air-conditioning units. The appearance and operation of a modern thermographic camera is often similar to a camcorder.
Often the live thermogram reveals temperature variations so clearly that a photograph is not necessary for analysis. A recording module is therefore not always built-in. Specialized thermal imaging cameras use focal plane arrays FPAs that respond to longer wavelengths mid- and long-wavelength infrared.
The newest technologies use low-cost, uncooled microbolometers as FPA sensors. Their resolution is considerably lower than that of optical cameras, mostly x or x pixelsup to x  for the most expensive models. Thermal imaging cameras are much more expensive than their visible-spectrum counterparts, and higher-end models are often export-restricted due to the military uses for this technology.
Older bolometers or more sensitive models such as InSb require cryogenic cooling, usually by a miniature Stirling cycle refrigerator or liquid nitrogen.
Thermal images, or thermograms, are actually visual displays of the amount of infrared energy emitted, transmitted, and reflected by an object. Because there are multiple sources of the infrared energy, it is difficult to get an accurate temperature of an object using this method. A thermal imaging camera is capable of performing algorithms to interpret that data and build an image.
Although the image shows the viewer an approximation of the temperature at which the object is operating, the camera is actually using multiple sources of data based on the areas surrounding the object to determine that value rather than detecting the actual temperature.
Emitted radiant power is generally what is intended to be measured; transmitted radiant power is the radiant power that passes through the subject from a remote thermal source, and; reflected radiant power is the amount of radiant power that reflects off the surface of the object from a remote thermal source. This phenomenon occurs everywhere, all the time. However, in the case of infrared thermography, the above equation is used to describe the radiant power within the spectral wavelength passband of the thermal imaging camera in use.
The radiant heat exchange requirements described in the equation apply equally at every wavelength in the electromagnetic spectrum. If the object is radiating at a higher temperature than its surroundings, then power transfer will be taking place and power will be radiating from warm to cold following the principle stated in the second law of thermodynamics. So if there is a cool area in the thermogram, that object will be absorbing the radiation emitted by the warm object.
The ability of objects to emit is called emissivityto absorb radiation is called absorptivity. Under outdoor environments, convective cooling from wind may also need to be considered when trying to get an accurate temperature reading.
The thermal imaging camera would next employ a series of mathematical algorithms. Since the camera is only able to see the electromagnetic radiation that is impossible to detect with the human eyeit will build a picture in the viewer and record a visible picture, usually in a JPG format.Lem live mod apk
In order to perform the role of non-contact temperature recorder, the camera will change the temperature of the object being viewed with its emissivity setting. Other algorithms can be used to affect the measurement, including the transmission ability of the transmitting medium usually air and the temperature of that transmitting medium.
All these settings will affect the ultimate output for the temperature of the object being viewed.
