Sensors Unlimited, Goodrich ISR Systems has introduced a 1.3 Megapixel, indium gallium arsenide (InGaAs) video camera, the GA-1280J-15A. The high-resolution J-Series SWIR camera features 1,280 x 1,024 pixels, with 15μm pitch and 60Hz full frame rate.
Compact (less than 4.3 cubic inches) and lightweight (less than 125g), the camera fits easily on board most unmanned aerial or ground vehicle systems, hand-held, and mobile surveillance systems. For added convenience, the camera is also available in an OEM model, which can be integrated into higher level systems.
The uncooled SWIR camera is available in two versions: one operates in the shortwave infrared from 0.9-1.7µm spectral range; the other offers extended NIR-SWIR range from 0.7-1.7µm. The cameras, which have no mechanical shutters, can image through fog, smoke, haze, or dusty conditions.
From low-light to daylight, the ruggedised, solid-state SWIR cameras are ideal for persistent surveillance and other military, aerospace, and marine operations. Both OEM camera models integrate easily into existing gimbaled or handheld imaging systems, enabling visual verification of laser location and imaging during thermal crossover – the hours of sunrise and sunset – when the performance of traditional thermal imaging systems is degraded.
The J-series SWIR camera features include on-board automatic gain control (AGC) and built-in non-uniformity corrections (NUCs). The internal circuitry of the ROIC and the dynamic range processing on board the camera address the challenges of urban night imaging without blooming. Camera Link digital output provides intuitive plug-and-play video operation with high quality 12-bit images for digital image processing or transmission.
