High school physics revisited
Infrared	radiation	 combines	 with	Gamma	 rays,	X-rays,	 Ultra	Violet,	 Visible	
Light,  Microwaves  and  Radio  Waves  to  form  a  range  of  energy  called  the 
Electromagnetic Spectrum. 
These  are  not  exotically  independent  types  of  energy  –  in  fact,  the  primary 
difference between each of these types of radiation is wavelength: Radio Waves 
have the longest wavelength and Gamma Rays have the shortest.  Wavelengths 
are measured in micrometers, or...

2) At a given temperature, the amount of thermal energy radiated by an object 
depends on its emissivity. Emissivity is the measure of an object’s efficiency at 
radiating thermal energy. For example, shiny metals are poor emitters. Instead 
of  radiating  their  own  thermal  energy,  they  tend  to  reflect  radiation  from  
their surroundings. 
Infrared, from theory to practical application
Infrared imagers operate by detecting the relative intensities of thermal energy 
radiated from the surfaces...

Thermal  energy  doesn’t  pass  through  much,  but  it  does  “transmit”  through 
some  plastics.  When  a  material  is  not  transparent  to  infrared  radiation, 
it  is  said  to  be  “opaque.”  Most  commonly  viewed  materials  are  opaque  to  
infrared radiation.
Materials  that  mirror  the  infrared  signatures  around  them  are  “reflective.”  
Ever y thing is reflective to one deg ree or another, but the most high ly reflective 
objects are those made of polished, unpainted metal....

conditions however, atmospheric moisture and dust scatter can absorb some of 
the radiated energy before it reaches the imager. The effect of this is to weaken 
the overall thermal signal and shorten the range at which you can detect it.  
The  weather  can  impact  more  than  just  the  range  at  which  the  Navigator  II  
can detect a specific object – it can also affect an entire scene’s thermal contrast 
and affect overall system performance.
Cloud cover affects the diurnal cycle in two ways:...
