Lämpökuvauksella

Lämpökuvauksella is a Finnish term that translates to "thermal imaging" or "thermography" in English. It refers to a non-destructive testing method that uses specialized cameras to detect and visualize infrared radiation emitted by objects. All objects with a temperature above absolute zero emit infrared radiation, and a thermal imaging camera captures this radiation and converts it into a visible image, often displayed as a heatmap where different colors represent different temperature variations.

The primary principle behind thermal imaging is the relationship between an object's temperature and the infrared radiation it emits. Warmer objects emit more infrared radiation than cooler objects. Thermal cameras, also known as infrared cameras or thermographic cameras, are equipped with a microbolometer or similar sensor that is sensitive to infrared wavelengths. This sensor detects the incoming radiation and processes it to create a thermal image.

Lämpökuvauksella has a wide range of applications across various fields. In building diagnostics, it is used to identify areas of heat loss, insulation defects, moisture intrusion, and air leaks, helping to improve energy efficiency. In industrial maintenance, it can detect overheating components in electrical systems, machinery, and industrial processes, preventing potential failures and ensuring safety. It is also used in the medical field for diagnostic purposes, in security and surveillance for detecting people or animals in low-light conditions, and in scientific research for studying temperature patterns. The interpretation of thermal images requires expertise, as factors like emissivity, reflectivity, and ambient temperature can influence the readings.
