The Science Behind Thermal Imaging: How Infrared Cameras Detect Heat

Thermal imaging technology has revolutionized industries ranging from security and defense to healthcare and wildlife monitoring. But how do infrared cameras detect heat? What is the science behind thermal imaging? This article delves into the fundamental principles of thermal imaging, explaining how infrared radiation enables these devices to visualize temperature variations and uncover details invisible to the human eye. What is Thermal Imaging? Thermal imaging is a technique that detects infrared radiation and translates it into an image, allowing us to see variations in temperature across a surface. Infrared cameras, also known as thermal cameras, function by capturing the infrared radiation emitted by objects. Unlike conventional cameras that rely on visible light, thermal cameras work in complete darkness, fog, or smoke. The Science Behind Infrared Radiation Infrared (IR) radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than mic…
