Black body radiation is the emission of electromagnetic energy by an object which is in a thermodynamic equilibrium. The blackbody emits an amount of energy depends on its temperature, with ideal blackbody absorbing and re-emitting all the incident radiations it receives at any wavelength.
Thermal imaging cameras comprise a vitally important technological category within military avionics, but they can only be used properly if they are calibrated and tested before being deployed. One of the simplest ways to carry out infrared measurement within the confines of electro-optical test systems is to use specially developed targets.
Testing the performance of imaging systems such as forward looking infrared radiometers (FLIR) is a vital task in the field of avionics, whether we’re talking about military or any other aircraft. The best way to examine the function of an imaging system is to use a systematized approach.
