The NIR/SWIR camera uses indium gallium arsenide-night vision (InGaAs-NV) technology to detect and track a broad range of battlefield infra-red lasers
Sensors Unlimited has released a night vision and laser detection camera that can see from the near infra-red (NIR) to the shortwave infra-red (SWIR) portions of the light spectrum, beyond what traditional night vision goggles can see.
The NIR/SWIR camera uses the company's indium gallium arsenide-night vision (InGaAs-NV) technology to detect and track a broad range of battlefield infra-red lasers with heightened night and day time sensitivity.
The NIR/SWIR cameras are being developed by the Sensors Unlimited team in Princeton, New Jersey within Goodrich's ISR Systems unit.
New processing techniques have pushed capabilities of the NIR/SWIR camera to see light wavelengths from 0.7 to 1.7 microns, whereas traditional night vision cameras can detect wavelengths up to roughly 1.0 microns.
NIR/SWIR's expanded capabilities allow the end user to detect and track a wide range of military lasers, including the covert eye-safe 1.5 micron laser.
Because InGaAS-NV technology detects light, unlike today's small thermal night vision cameras that detect heat signature, the NIR/SWIR camera provides exceptional clarity in both day and night use.
The system is available in small, lightweight camera packages with 320 x 256 or 640 x 512 resolution.
The NIR/SWIR cameras are suitable for integration into night vision and laser detection systems on unmanned aerial or ground vehicles, rifle scopes, precision guided munitions and hostile fire indicators.
Potential industrial applications include machine vision to detect moisture, manufacturing imperfections, integrity of seals or joints and other characteristics that affect product quality.
