Hyperspectral imaging is particularly useful in military surveillance because of countermeasures that military entities now take to avoid airborne surveillance. The idea that drives hyperspectral surveillance is that hyperspectral scanning draws information from such a large portion of the light spectrum that any given object should have a ...
The passive hyperspectral imaging spectroscopy remote sensor observes a target in multi-spectral bands. The HSI camera separates the image spectra into 52 "bins" from 500 nanometers (nm) wavelength at the blue end of the visible spectrum to 1100 nm in the infrared, giving the camera a spectral resolution of 11.5 nm.

He also listed a contract position with General Dynamics from 2011 to 2012 as a hyperspectral imaging integrator, during which he “engineered and fielded the first mobile standoff hyperspectral ...
Hyperspectral imaging from aircraft or satellites can provide remotely sensed reflectance spectra to help detect such graves. Imaging of an experimental mass grave and a real-world mass grave show that hyperspectral remote imaging is a powerful method for finding mass graves in real time, or, in some cases, retrospectively.

The spectrometer uses the ARTEMIS hyperspectral imaging sensor (HSI), which is a single HgCdTe Focal Plane Array covering the entire V/NIR/SWIR spectrum from 400 nm to 2500 nm at a uniform resolution of 5 nm. ARTEMIS measures first the spectral information at each point on the ground in 400 spectral channels.
A subset of spectral imagery, hyperspectral imaging data, is produced when "solar electromagnetic energy reflected from the earth's surface is dispersed into many contiguous narrow spectral bands by an airborne spectrometer" (Stefanou, 1997, p. 2). Our current research and projects include environmental mapping, target detection, and change ...
The EO system utilizes a CCD camera and an embedded imaging computer to obtain the desired images while accounting for the movement of the aerial system to which it is attached. [ 2 ] [ 3 ] The digital camera is able to operate at exposures as short as 1/4000 sec, eliminating motion blur for images acquired at typical ground velocities of 110 ...
Gaofen-5 has been lauded as the "flagship of the environment and atmosphere observation satellite in the CHEOS program". Launched on 8 May 2018 from Taiyuan Satellite Launch Center (TSLC) into Sun-synchronous orbit, Gaofen-5 carries six payloads: an Advanced Hyperspectral Imagery sensor (AHSI), Atmospheric Infrared Ultraspectral Sensor (AIUS), Directional Polarization Camera (DPC), Environment ...
