Infrared imaging is a technology that captures images using infrared radiation, which is not visible to the human eye. This method 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 images produced by infrared cameras show variations in temperature, helping to identify issues like heat loss in buildings or abnormal body temperatures in patients. This non-invasive technique provides valuable information without needing direct contact, making it a useful tool in both industrial and medical applications.
