Thermal imaging, also known as infrared imaging, is a technology used to produce an image based on the amount of infrared radiation emitted, reflected, or transmitted by an object. It provides a visual representation of temperature differences on objects in a scene, allowing detection of hidden problems, inspection of equipment and machinery, monitoring of building energy efficiency, search and rescue operations, and more. Thermal cameras typically use a specialized sensor to detect infrared radiation and convert it into an electronic signal, which is then processed into a thermal image that highlights temperature differences as different colors on a display screen.
