What is a thermographic camera?

Definition and explanation of how it works

Thermographic cameras, also known as infrared cameras or thermal imaging cameras, are devices that use infrared radiation to create images of an object or scene. This type of camera detects the temperature differences between different parts of an object or scene and then translates this information into a visual image.

The way thermographic cameras work is based on the fact that every object emits some level of infrared radiation, which corresponds to its temperature. The camera then detects this radiation and uses it to create the image.

The hotter an object is, the more infrared radiation it will emit and appear brighter in the image. Thermographic cameras have a lens that focuses incoming infrared radiation onto a detector array made up of thousands of tiny infrared sensors called microbolometers.

Each sensor detects the temperature at its specific location on the lens’s field of view and sends this information to a signal-processing unit. The unit processes these signals into electrical impulses, which create a visual representation on the display screen.

Types of thermographic cameras available in South Africa
