2. Multispectral imaging - Wikipedia

   en.wikipedia.org/wiki/Multispectral_imaging

   MWIR presents a strong signal from highly heated objects including rocket plumes, while LWIR produces emissions from the missile's body material. The US Army Research Laboratory reported that with their dual-band MWIR/LWIR technology, tracking of the Atlas 5 Evolved Expendable Launch Vehicles, similar in design to ICBMs, picked up both the ...

3. Infrared - Wikipedia

   en.wikipedia.org/wiki/Infrared

   Infrared light from the LED of a remote control as recorded by a digital camera. A hyperspectral image is a "picture" containing continuous spectrum through a wide spectral range at each pixel. Hyperspectral imaging is gaining importance in the field of applied spectroscopy particularly with NIR, SWIR, MWIR, and LWIR spectral regions.

4. Thermography - Wikipedia

   en.wikipedia.org/wiki/Thermography

   Hence, an excellent way to measure thermal variations is to use an infrared vision device, usually a focal plane array (FPA) infrared camera capable of detecting radiation in the mid (3 to 5 μm) and long (7 to 14 μm) wave infrared bands, denoted as MWIR and LWIR, corresponding to two of the high transmittance infrared windows. Abnormal ...

5. Forward-looking infrared - Wikipedia

   en.wikipedia.org/wiki/Forward-looking_infrared

   Many thermal imagers, including some forward-looking infrared cameras (such as some LWIR enhanced vision systems (EVS)) are also uncooled. Medium-wave (MWIR) cameras operate in the 3–5 μm range. These can see almost as well, since those frequencies are less affected by water-vapor absorption, but generally require a more expensive sensor ...

6. Infrared vision - Wikipedia

   en.wikipedia.org/wiki/Infrared_vision

   Infrared vision is the capability of biological or artificial systems to detect infrared radiation. The terms thermal vision and thermal imaging [ 1 ] [ 2 ] are also commonly used in this context since infrared emissions from a body are directly related to their temperature: hotter objects emit more energy in the infrared spectrum than colder ones.

7. Visible spectrum - Wikipedia

   en.wikipedia.org/wiki/Visible_spectrum

   The optical window is also referred to as the "visible window" because it overlaps the human visible response spectrum. The near infrared (NIR) window lies just out of the human vision, as well as the medium wavelength infrared (MWIR) window, and the long-wavelength or far-infrared (LWIR or FIR) window, although other animals may perceive them ...

8. Mercury cadmium telluride - Wikipedia

   en.wikipedia.org/wiki/Mercury_cadmium_telluride

   Detection in the MWIR and LWIR windows is obtained using 30% [(Hg 0.7 Cd 0.3)Te] and 20% [(Hg 0.8 Cd 0.2)Te] cadmium respectively. HgCdTe can also detect in the short wave infrared SWIR atmospheric windows of 2.2 to 2.4 μm and 1.5 to 1.8 μm. HgCdTe is a common material in photodetectors of Fourier transform infrared spectrometers. This is ...

9. Enhanced flight vision system - Wikipedia

   en.wikipedia.org/wiki/Enhanced_flight_vision_system

   A SWIR (short-wavelength infrared) camera is a relatively new technology. It can offer advantages for an EFVS, such as: better haze penetration than VIS, natural scene contrast similar to VIS unlike a MWIR or LWIR. SWIR cameras are available commercially, but there is no reported use of a SWIR camera in a commercial EFVS.
