Thermal imaging used infrared radiation and thermal energy to formulate images. It is a good way to gather images in low-visibility environments and can be utilised for many applications.
Thermal imaging cameras work by detecting the infrared radiation emitted from a person or object to create an image. This is otherwise known as a heat signature.
Cameras are fitted with a lens that picks up infrared frequencies allowing the camera to read and detect the signatures. Heat sensors will pick up minuscule differences in temperature, making them highly effective.
The image then shows where objects are and their temperature in relation to the environment they are in by colour.
Most thermal images are in greyscale, with white indicating the presence of heat whereas black indicates coldness.
However, some will show an image in colour. Blue will indicate cold, red will indicate hot. There are many colours on the colour map and images will often contain all colours of the rainbow.
There are many uses for thermal imaging. Security cameras utilise thermal imaging as they are able to locate heat sources in difficult to see places and during the night. This makes it nearly impossible for intruders to escape, regardless of how hidden they think they are.
It can also be used in many practical applications, such as locating air or water leaks. This is useful when you cannot find the source of a leak that needs treating.
Thermal imaging also helps pinpoint reasons for heat loss caused by poor insulation, highlighting areas that need further work.
Another use is electrical maintenance. Thermal imaging can help locate faults in electrical systems that are otherwise invisible to the human eye. This is especially effective when dealing with potentially dangerous electrical issues.
