Long Wave Infrared Hyperspectral Sensor

While a sensor with 20 discrete bands covering the visible near short wave medium wave and long wave infrared would be considered multispectral.

Long wave infrared hyperspectral sensor.

The us air force usaf has awarded a contract to bodkin design engineering bd e for the development of a high spatial resolution long wave infrared lwir hyperspectral sensor system. Hyperspectral imaging measures the spatial and spectral characteristics of an object by imaging it at different wavelengths. Current hyperspectral system capabilities are limited by variation in the background clutter as opposed to the physics of photon detection. Wright author affiliations.

8 to 12 or 7 to 14 μm this is the atmospheric window covered by hgcdte and microbolometers. Lwir surveys are sometimes referred to as thermal imaging and can be used to identify relatively warm features such as hot springs fumaroles and snow melt. The airborne platform is equipped with a stabilization system and an image motion compensation mirror which allows you to use the hyper cam from an airplane in order to map vast areas and obtain clear high quality spectral information. Getting started with hyperspectral image processing.

Very long wave infrared vlwir 12 to about 30 μm covered by doped silicon. The hyper cam can be used as an advanced hyperspectral imaging solution for airborne infrared spectroscopy. 31 may 2013 a long wave infrared hyperspectral sensor for shadow class uavs p. Introduction this paper describes the development of a non contact sensing capability for on the move detection of surface contaminants.

Near infrared is the region closest in wavelength to the radiation detectable by the human eye. Long wave infrared lwir refers to multi and hyperspectral data collected in the 8 to 15 µm wavelength range. Long wave infrared lwir hyperspectral imaging sensors are widely used for the detection and identification of released chemical agents in many civilian and military applications. Lucey jason t.

Mid and far infrared are progressively further from. The wavelength range extends beyond the visible spectrum and covers ultraviolet uv to long wave infrared lwir wavelengths.
