Design of a multispectral, wedge filter, remote-sensing instrument incorporating a multiport, thinned, CCD area array

TLDR: The next generation Wedge Imaging Spectrometer (WIS) instruments as discussed by the authors incorporate advanced features to increase operation flexibility for remotely sensed hyperspectral imagery collection and use, such as multiple linear wedge filters to tailor the spectral bands to the scene phenomenology; simple, replaceable fore-optics to allow different spatial resolutions and coverages; data acquisition system (DAS) that collects the full data stream simultaneously from both WIS instruments (VNIR and SWIR/MWIR), stores the data in a RAID storage, and provides for downloading of the data to MO disks

Abstract: The next generation Wedge Imaging Spectrometer (WIS) instruments currently in integration at Hughes SBRD incorporate advanced features to increase operation flexibility for remotely sensed hyperspectral imagery collection and use. These features include: a) multiple linear wedge filters to tailor the spectral bands to the scene phenomenology; b) simple, replaceable fore-optics to allow different spatial resolutions and coverages; c) data acquisition system (DAS) that collects the full data stream simultaneously from both WIS instruments (VNIR and SWIR/MWIR), stores the data in a RAID storage, and provides for down-loading of the data to MO disks; the WIS DAS also allows selection of the spectral band sets to be stored; d) high-performance VNIR camera subsystem based upon a 512 X 512 CCD area array and associated electronics.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
