White Paper: Expanding The Dynamic Range Of Short Wave Infrared (SWIR) Imagery

By Marc Hansen, Sensors Unlimited, Inc.

Advances have been made in short wave infrared (SWIR) imaging technology to address the most demanding imaging and surveillance applications. Multiple techniques have been developed and deployed in Goodrich’s SWIR indium gallium arsenide (InGaAs) cameras to increase the dynamic range performance of standard, commercial off-theshelf (COTS) products. New developments have been implemented on multiple levels to give these cameras the unique ability to automatically compensate for changes in light levels of up to five orders of magnitude, while improving intra-scenic dynamic range through raw data acquisition techniques, and a proprietary, patent-pending, image-enhancement algorithm.
