How heat transfer relates to thermal imaging

Methods of heat transfer

Heat energy can be transferred in three basic ways: conduction, convection and radiation. Thermal imagers, or infrared cameras, can only detect radiated heat energy, so it’s important to understand the distinction so you know the limitations of your thermal imaging device.

All objects radiate electromagnetic energy at the speed of light. Electromagnetic energy is radiated in waves with electric and magnetic properties. It can take on several forms including light, radio waves, and infrared radiation. The primary difference among all of the wave types is their wavelength. Normal eyesight detects visible light wavelengths, while infrared cameras detect radiated heat (or infrared radiation) wavelengths.

To understand this topic more thoroughly, we recommend you seek out training, which can provide you with the theoretical and practical tools to get the best results out of your thermal camera.
