Recent LWIR studies have shown that imaging
in
the long-wave infrared spectral region delivers performance that is otherwise
unrealizable
by other infrared imaging means.
Primary reasons for LWIR imaging success:
- As can be seen by Planck's blackbody
characteristics, objects at or near room temperature
have peak emission in the LWIR spectral range.
- Because of technological advances in
infrared FPA technology, cooled MCT infrared detectors
are now available that exhibit LWIR performance that
exceeds 90% quantum efficiency in that spectral range.
- Under certain conditions, LWIR imaging is preferred
due to high transmissivity through the atmosphere
as well as through smoke and fog.
For these reasons, long-wave
MCT-based infrared cameras have found many new applications,
including:
- IR imaging of objects at great distances
- Temperature measurement of high-speed
events
- Observation of wide dynamic range scenes
- Infrared imaging of very cold objects
