Thermal Imaging

Source: Department of Energy Understanding Thermal Imaging Thermal imaging, also known as infrared thermography, involves capturing images based on thermal radiation emitted by objects. This technology is used to either measure accurate temperature maps of surfaces or to provide qualitative information such as identifying hot spots without precise temperature measurements. Principles of Thermal Imaging Thermal […]

Emissivity

Source: CleverIR Emissivity in Photonics The Concept of Emissivity Emissivity is a crucial concept in the field of photonics, determining how effectively an object interacts with thermal radiation by emitting and absorbing it. It is quantified on a scale from 0 to 1 and can vary based on factors such as optical frequency, wavelength, incidence
