Reflectivity-and commonly, the word reflectance-refers to the amount of incident radiant energy is mirrored or reversed from a material surface.
A bolometer is a sensor physically much like a common photographic CMOS or CCD sensor, except that it employs a different transduction process and is sensitive to a very broad range of electromagnetic energy
The effects of atmospheric media on thermography will be dependent upon its temperature, density, movement, particulates, etc.
The discharge of electromagnetic energy is known as electromagnetic radiation.
“Electromagnetic energy” is the name given to radiating, self-propagating, co-occurring electric and magnetic fields.
The lowest theoretical temperature of matter is a threshold at which a mass has no surplus kinetic energy to transfer. That state is known as “Zero Kelvin.”
Convection refers to the movement of gas or fluid due to differences in density (gravity, natural convection) or physical force (mechanical convection).
Emissivity is widely considered to be the single most crucial parameter in thermographic praxis.
A widely accepted conventional wisdom is that temperature is the most commonly measured parameter within industry.
Thermodynamics is the science of relationships between energy, temperature, and work. Thermography is an aspect of applied thermodynamics.
Germanium, a semi-metallic element (atomic number 32, symbol Ge) is highly suitable for midwave and longwave infrared optics even though it is obviously opaque to visible band light.
Enthalpy refers to the total energy of all types in a thermodynamic system.
