Recent studies have shown that imaging
in the long-wave infrared (LWIR) spectral region with cooled photovoltaic
infrared detectors has the ability to deliver remarkable performance
that is otherwise unrealizable by any other infrared imaging means.
Examples as shown below include:
Acquiring infrared target
signatures at a great distance
Viewing high speed thermal events
High dynamic range infrared imaging (cold
and hot objects in one frame)
Because an object's radiation drops in proportion
to the cube of its distance, and due to atmospheric windows
in the LWIR band, only very sensitive LWIR imaging can detect
radiation from objects at great distances.
In order to accurately measure the temperature
of high speed events, LWIR imaging permits the analysis of the
radiation from objects for times as short as a few microseconds.
When observing scenes having very wide temperature
ranges (from ambient to >2000K), imaging in the LWIR band
delivers superior results (attributable to the relatively small
flux distribution in the LWIR band when compared to the MWIR
band).
Many infrared scenes involve imaging scenes having very little
infrared radiance such as with the cold atmosphere or winter
climates. LWIR imaging is a necessity for imaging in these situations.
