WebUnfortunately, because the emissivity of a material surface depends on many chemical and physical properties, it is often difficult to estimate. It must either be measured or modified in some way, for example by coating the surface with high emissivity black paint, to provide a known emissivity value.

WebA surface with a low emissivity value (i.e. aluminium, steel, etc.) acts as a mirror (high reflectance). However, such problem is usually overcome using high emittance flat paints (i.e. black colour water based paints) for painting the investigated surface(s). Infrared thermography is deployed by two approaches; passive and active.
