InGaAs SWIR Video Camera Integrated on Unmanned Aircraft Test Flight

Sensors Unlimited, Inc., part of Goodrich Corporation (Princeton, N.J.), announced that its ultra-compact, high sensitivity SU640KTSX indium gallium arsenide (InGaAs) shortwave infrared (SWIR) camera has been successfully flight-tested on the ScanEagle unmanned aircraft at the Fort Leonard Wood test range in Missouri. The InGaAs-SWIR imager requires no cooling, is lightweight (less than 90g) and uses low power (less than 2.5W at 20 degrees C.), making it ideal for unmanned flight imaging requirements.

The flight test was in conjunction with The Boeing Co. (Integrated Defense Systems, St. Louis, Mo.), and Insitu (Bingen, Wash.) Ed Hart, General Manager of Goodrich's Sensors Unlimited team, says, "The ability to image through many atmospheric obscurants like fog, haze or rain during daytime or nighttime makes our shortwave InGaAs high sensitivity camera especially useful for unmanned aircraft for maritime intelligence and surveillance, says Ed Hart, GM of Goodrich's Sensors Unlimited team.

The 640 x 512 pixel solid-state camera, with on-board non-uniformity corrections, captures full-sized images at 30 frames per second. The camera's focal plane array features a 25-micron pitch with a wavelength response over the shortwave infrared spectrum from 0.9 to 1.7 microns. This model is also available with Sensors Unlimited's new NIR/SWIR extended wavelength response from 0.7 to 1.7 microns. The SU640KTSX easily can be integrated into large or small systems, making it suitable for hand-held, helmet mounted, mobile or aerial SWIR imaging applications. Because InGaAs night vision technology detects reflected light, unlike today's small thermal night vision cameras that detect heat signatures, Goodrich's compact NIR/SWIR camera provides exceptional identification clarity over a wide range of day and night illumination levels.

Goodrich's Sensors Unlimited Inc. team, based in Princeton, NJ, has pioneered the design and production of NIR and SWIR cameras and systems utilizing advanced Indium Gallium Arsenide (InGaAs) imaging technology for industrial, commercial, military, agricultural, and scientific markets.
