Lessons in physics have talked something about the colors we see as being only reflections from the objects that possess it. To illustrate, red objects may have just been reflecting the color red. The objects do not really differ in color per se, but in their compositions that cause them to reflect different colors. This may sound so bizarre but this really is the case. But when it comes to Thermal Imaging technology, what is being reflected is not what is important. What’s important is what the objects emit-which is oftentimes, heat.
How does the Thermal Imaging technology work? This really is not very simple to explain. Light is said t travel in wavelengths. Wavelengths depend on the amount of energy that it contains. The shorter the wavelength, the higher is its energy content, the higher also its visibility. In visible light, of the seven colors, violet has the most energy (or frequency) while red has the least. When night falls and light fades, all these colors will lose energy, making it harder to see objects. Thermal Imaging technology comes in here. This tries to make sense of light whose frequencies are well below red, light that is just invisible to the human eye. These light frequencies are called infrared.
Infrared frequencies or simply, heat are said to be emitted by all objects-living or not. This is mainly because of what’s happening in the atomic label. As you may have learned from high school, almost everything that involves energy produces heat as a by-product. Obviously, the atoms in the objects that are around are in constant motion. From this, it is obvious that they are in constant use also of energy. And this usage produces the emissions that make only the Thermal Imaging Technology can make sense of.
Now that you know how Thermal Imaging technology works in its most basic sense, it is just appropriate to discuss next its uses. As you may have seen in films, this type of technology is really useful in, what else, seeing in the dark. Because this is very reliant on heat, the warmer the objects are, the easier it is for them to be detected by any Thermal Imaging Technology. So as depicted in war films, it really is very easy for the lead characters to see their enemies in the dark, and that is simple because they are living things and are therefore a lot warmer than the objects that surround them.
Another important use of thermal imaging technology is in energy auditing and insulation. This technology is now used to determine how much a building or a house needs insulation to save energy. Through thermal imaging, an energy auditor would know which part of the house is hot or is wasting a lot of energy. Then, the energy auditor would inspect that part of the house for leaks or cracks on walls. This process is important prior to installing insulation materials such as foam or fiberglass.
