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.
A blackbody is a conceptual solid mass that absorbs all electromagnetic radiation incident upon it, at all angles and all wavelengths.
Pixel is a portmanteau of “picture element” and is generally understood to refer to the granular spatial component of a common electromagnetic sensor.
The blend of reflected, transmitted, and emitted energy from a surface does not represent the temperature of a surface; only the emitted energy fraction has that opportunity.
Electromagnetic energy will behave in one or more of three ways when it is incident upon an object or encounters a medium boundary; it will either be absorbed, be reflected, or be transmitted.
Convection is the movement of a gas or fluid due to differences in density (gravity, natural convection) or physical force (mechanical convection).
In fact, thermography doesn’t even measure temperature!
Contrary to conventional wisdom, thermography does not measure temperature.

The images below represent some interesting results from both vertical (orthogonal) and oblique aerial thermography throughout 2018.
The EPA has established a Heat Island Reduction Program (HIRP) and expressed that it is useful for communities in the preparation of projects, programs, and policies. While this language is nurturing vice systemizing, the statement is contained in a section titled “What EPA is Doing to Reduce Heat Islands.” An intent is obvious, and it must be considered that EPA is not a hobbyist organization.
For the FLIR T10xx camera series lenses typically offer very low focal length ratios. The common 36mm/28°HFOV lens aperture is fixed at f1.15, while the less common 83.4mm/12°HFOV lens is fixed at f1.2.
It is a generally accepted principle to adjust the “exposure” of professional thermograms so that the bulk of the selected palette range is confined to features of interest in order to produce the finest representation of their thermal patterning.
