Thermal imaging cameras have been around for quite a while, but very few actually get to use them on a daily basis and even fewer people truly understand how they operate. Today we are going to explain what thermal imaging cameras are about, and we are going to answer the following questions: what is a thermal imaging camera?, what are the main features of a thermal imaging camera? and what are thermal imaging cameras used for? Keep reading and find out how using thermal imaging cameras can help you to #ONEUPYOURBUSINESS.
Thermal imaging cameras were developed during the Korean War, and like many other pieces of technology, they soon were used by the civilians for a wide variety of purposes.
The human eye sees a specific portion of the light spectrum. In reality, the amount and type of light our eyes can perceive is quite limited. In order to visualise infrared radiation and the electromagnetic spectrum we have to use dedicated equipment. This is the main use of a thermal imaging camera, which transforms heat into a visible light source that is projected on the different objects’ surfaces.
By displaying the temperature visually, inspectors have a truly powerful tool to assess the different temperature values quickly and efficiently. With a thermal imaging camera you can easily identify heat sources, wet spots, people, animals, etc.
The technical term for a thermal image is thermogram, and the process of analysing them is known as thermography.
In its most simplistic form, a thermal imaging camera will only measure the temperature in the very centre of the image, but the more advanced units, like the ones that we use, will take differential values from multiple points, giving maximum, minimum, median and range values.
With some of the more advanced units, we can select different colour palettes, overlay the thermal image on top of a normal image or even combine both within the same image.
For concrete tasks, depending on the camera, we can set the range of temperatures that we know we have to look for, eliminating any possible unused values and focusing on what matters for that specific inspection.
Besides its original military applications, thermal imaging cameras are used for a wide variety of purposes: search and rescue, crime fighting, building surveys, energy reports, etc.
For the Construction, Property, Insurance, Energy, and Agriculture sectors, the main uses of a thermal imaging camera are:
