But how does this work?
As a function of their temperatures, all objects emit a certain amount of black body radiation. In general, the higher the temperature of an object, the more infrared radiation is emitted as black-body radiation. These form images and a special camera can detect this radiation. On infrared cameras, the warmest parts of the image are white, intermediate temperatures are in reds and yellows, and the coolest parts are black.
These days, infrared camera is use in many applications like:
- To locate people or hotspots of fire
- To monitor fever
- To aid the driver in some luxury cars
- Enhance night vision
In building inspections, thermal imaging can inform technicians of a faulty thermal insulation or heat leaks. Heat loss that is invisible to the naked eye is detected. Locating such patterns and sources enables them to see where improvements need to be made. Thermal imaging camera is also used in roof inspection, moisture detection, wall structural analysis, auditing of building insulation, detection of leaks.
