1 January 1987 Airborne Imaging Spectrometer II: The Optical Design
Author Affiliations +
The Airborne Imaging Spectrometer (AIS I) was a multispectral infrared imaging instrument utilizing a 32 x 32 element mercury-cadmium-telluride detector array. A novel optical design provided high spectral resolution and, in conjunction with the 32-element spatial resolution, made optimal use of the capabilities of the area array. The operational successes of this proof-of-concept instrument, coupled with advances in infrared detector array technology, have provided the impetus and opportunity to upgrade the instrument by replacing the sensor with a newly developed 64 x 64 detector. The original instrument configuration is reviewed, and the design considerations, limitations and trade-offs necessitated by the new detector are examined, particularly the near doubling of the field of view and the increase from 1024 to 4096 pixels per read-out frame.
