lämpökuva

Lämpökuva, also known as thermal imaging or thermography, is a technique used to visualize infrared radiation emitted by objects. This radiation, invisible to the human eye, corresponds to the heat of an object. A thermal imaging camera, or infrared camera, detects this radiation and converts it into a visual image, where different colors represent different temperatures. Typically, warmer objects appear in brighter colors like red or yellow, while cooler objects are depicted in darker shades such as blue or purple.

The applications of lämpökuva are widespread. In construction, it is used to detect heat loss in buildings, identify insulation defects, and locate water leaks. In the industrial sector, it helps in monitoring the performance of machinery, identifying potential overheating in electrical components, and inspecting pipelines. In medicine, thermal imaging can aid in diagnosing circulatory problems, detecting inflammation, and monitoring wound healing. It also finds use in security for surveillance in low-light conditions, in research for studying heat transfer, and even in animal tracking. The ability to see heat signatures without physical contact makes lämpökuva a valuable non-destructive diagnostic tool.
