As technology has evolved in numerous areas, one aspect that has become useful in many areas has been thermography. Also known as digital infrared thermal imaging, it relies on being able to detect varying levels of radiation using specialized cameras. By doing so, it allows those using the technology to see details of rooms, human bodies, and other things without having them visibly illuminated. First developed in 1965, it has been used in many medical facilities since the 1970s and has also found its way into many other areas. To gain a greater understanding of thermography, here are some key points to remember.
Variations in Temperature
To be effective, thermography detects how the amount of radiation in and around an object increases or decreases in temperature. As a result, it allows a person using a special thermal imaging camera to see variation in temperature, which is displayed on the camera by warm areas showing up as red or yellow, while cooler areas are shown as blue. Easily used during both day and night, it has become an effective tool in numerous industries.
How is it Used?
Since thermography has developed into a very reliable technology, it has found its way into more and more industries over the years. One of the most crucial has been medicine, where it has been used primarily to help doctors detect breast cancer. Along with this, doctors also use it to evaluate patients complaining of unexplained pain, such as those with headaches or back injuries. In addition to its medical uses, firefighters also use it when entering smoke-filled buildings to locate victims, military personnel use it for night vision goggles, and maintenance technicians use it to conduct inspections of buildings to find leaks in pipes, areas where heat is being lost, and when inspecting various sloped and flat roofing.

Advantages of Thermography
Since it is able to be used in such a wide variety of applications, it’s clear thermography has many advantages. Some of these include its ability to display a picture over a large area, showing images in real-time, being used in areas that are hard to access or considered to be too dangerous for people to enter, and its accuracy and reliability as a safe, non-destructive method of testing. As its use in medicine has expanded over the years, thermography has been credited with saving numerous lives, by enabling doctors to detect breast cancer and other diseases much quicker than in years past. And along with this, it has also made the jobs of police officers, firefighters, military soldiers, and others in high-risk fields much easier and safer as well.

Limitations of Thermography
While thermography is used very effectively in many various situations, it does have some limitations. For example, many of the best cameras can be very expensive, costing over $3,000. However, these cameras are often necessary, since they offer a larger pixel array, making the picture much clearer. Along with this, accurate measurements can sometimes be difficult to ascertain in certain environments, especially those where reflections may be present. And finally, accuracy may be hindered in areas where temperatures may be very erratic or unstable, although recent technological advances have made this problem much less severe.
Future of Thermography
As thermographic technology becomes more and more advanced, it’s expected to be used in many additional fields. Some of these include veterinary medicine, where it will be able to detect cancer and other diseases and conditions in various animals. In addition to this, thermography will also play a vital role in volcanology, helping scientists gain a greater understanding of how volcanoes work and when they may erupt. And perhaps most importantly, thermography is being used to help engineers design many alternative forms of energy, particularly solar panels. By using this technology, engineers can more accurately assess which parts of a solar panel are stronger than others, allowing them to make changes before the panel is installed. By implementing this technology into various areas in the years ahead, it’s clear there will be even more advancements made along the way, helping people in many ways.
