Short Wave Infrared

3 to 5 μm defined by the atmospheric window and covered by indium antimonide insb and mercury cadmium telluride hgcdte and partially by.
Short wave infrared. 1 0 to 3 μm from the cut off of silicon to that of the mwir atmospheric window. This band is mainly helpful for discriminating among different types of rock formations. 1 400 1 900 and 2 400 nanometers. The more water there is even in soil the darker the image will appear at these wavelengths.
It can also be used to measures the infrared radiant flux heat amount emitted from the surfaces. Since silicon sensors have an upper limit of approximately 1 0μm swir imaging requires unique optical and electronic components capable of performing in the specific swir range. Sensors unlimited inc part of utc aerospace systems is the pioneer in this technology and clear leader in advancing the capability of swir sensors. This wavelength is not visible to human eyes and as a result can often offer a better image than what is achievable with visible light imaging.
Ingaas covers to about 1 8 μm. Water absorbs shortwave infrared light in three regions. Short wave infrared swir light is typically defined as light in the 0 9 1 7μm wavelength range but can also be classified from 0 7 2 5μm. This band is particularly responsive to the vegetation biomass that is present in the image.
Short wave ir swir is a subset of the infrared band in the electromagnetic spectrum covering the wavelengths ranging from 1 4 to 3 microns.
