Introduction to Thermal Imaging

Thermal imaging, also known as infrared thermography, is a technology that detects infrared radiation (heat) emitted by objects and converts it into a visible image. Every object with a temperature above absolute zero emits infrared radiation. Thermal imaging cameras can capture this radiation and create a visual representation of the temperature distribution across an object or a scene. This technology has a wide range of applications, including military and defense, industrial inspection, building diagnostics, medical imaging, and wildlife monitoring.
