Infrared imaging is a technology that captures images using infrared radiation, which is not visible to the human eye. This type of imaging detects heat emitted by objects, allowing us to see temperature differences. It is commonly used in various fields, including medical diagnostics, building inspections, and surveillance. The process involves using an infrared camera that converts infrared radiation into an electronic signal, creating a visual representation of the heat patterns. This can help identify issues like heat loss in buildings or detect abnormalities in the human body, making it a valuable tool for both professionals and researchers.
