Abstract

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 optimize the dynamic range performance of standard, commercial off-the-shelf (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 over more than 5 orders of magnitude, while improving intra-scenic dynamic range. Features recently developed and implemented include a new Automatic Gain Control (AGC) algorithm, image flash suppression, and a proprietary image-enhancement algorithm with a simplified but powerful user command structure.
