UTC Aerospace Systems, a unit of United Technologies Corp., introduced its next generation Sensors Unlimited shortwave infrared (SWIR) digital video camera at AUVSI Unmanned Systems North America Exhibition on 6-9 August in Las Vegas, Nevada (US).
This high-resolution, indium gallium arsenide (InGaAs) mil-rugged digital video camera, the model GA1280JS, features 30 hertz (Hz) full-frame rate with a global shutter function, featuring a high-sensitivity of 1.3 megapixel resolution at 1280 × 1024 pixels and a 12.5 micron pitch. It also adds snapshot mode capability to the Sensors Unlimited high-definition SWIR product range.
The camera is lightweight (less than 120 grams or 4 ounces without lens) and compact (less than 4.5 cubic inches or 74 cubic centimeters), allowing for easy integration into aerial, mobile and hand-held imaging systems. It provides real-time daylight to low-light imaging (including partial moonlight) in SWIR with high sensitivity in the 0.9 to 1.7µm microns. The optional near infrared (NIR)/SWIR model operates from 0.5 to 1.7µm spectrum. The InGaAs-SWIR sensor images through atmospheric obscurants, such as smoke, fog and haze. All solid state, the J-series cameras require no cooling; they also feature on-board, automatic gain control (AGC) and real-time non-uniformity corrections (NUCs), making it possible to address the challenges of urban night imaging without blooming.
The 12-bit digital base with CameraLink output provides intuitive plug-and-play functionality. The improved dynamic range enhancements make the new camera well suited for local area image processing and transmission. The GA1280JS camera has been rigorously tested to MIL-STD-810G for functional shock, vibration, thermal shock, storage temperature, altitude, humidity and acceleration.
