lämpökuvantamisen

Lämpökuvantaminen, often translated as thermography or thermal imaging, is a non-contact method used to detect and visualize infrared radiation emitted by objects. All objects above absolute zero temperature emit infrared radiation, and the intensity and wavelength of this radiation are dependent on the object's temperature. A thermal imaging camera, also known as an infrared camera or thermographic camera, captures this emitted radiation and converts it into a visible image.

The resulting image, called a thermogram, displays different colors or shades of gray to represent different temperature levels. Typically, warmer areas are depicted with brighter or warmer colors (like red or yellow), while cooler areas are shown with darker or cooler colors (like blue or purple). This allows for the identification of temperature variations across a surface or within an object.

Thermography finds applications in a wide range of fields. In building diagnostics, it's used to identify heat loss, insulation defects, and air leaks, as well as moisture detection. In industry, it's employed for predictive maintenance, checking electrical connections, motor bearings, and other equipment for overheating that could indicate potential failure. Medical thermography can be used to detect inflammation or circulatory problems. Firefighting utilizes thermal cameras to see through smoke and locate heat sources. Electrical inspections, research and development, and even wildlife monitoring are other areas where thermal imaging is a valuable tool. The ability to visualize temperature differences without physical contact makes it a safe and efficient diagnostic technique.
