5 Best Thermal (Infrared) Drones

What is thermal imaging? What is infrared imaging? Thermal Imaging sensors are commonly referred to with terms such as thermal camera, temperature camera, heat vision camera, infrared camera, heat signature camera, and even thermal heat vision sensor. In this post, we will refer to this type of imaging as infrared or thermal imaging. All objects (above absolute zero) emit infrared energy as a function of their temperature. The vibration of atoms and molecules generates infrared energy. The higher the temperature of an object, the faster its molecules and atoms move. This movement is emitted as infrared radiation, which our eyes cannot see but our skin can feel (as heat). Thermal imaging uses special infrared camera sensors to illuminate a spectrum of light invisible to the naked eye. Thermal energy is invisible to the naked eye and works in different ways; it can be emitted, absorbed, or reflected. Infrared cannot see through objects but can detect differences in radiated thermal energy between materials. This is known as thermal bridging or heat transfer. To sum it all up, thermal imaging cameras are precise non-contact temperature measurement devices.
