PRINCETON, N.J., Sept. 7, 2010 — Goodrich Corp.’s ISR Systems’ Princeton team (formerly Sensors Unlimited Inc.) has introduced the smallest size, weight and power (SWaP) short-wavelength infrared (SWIR) camera for unmanned aerial vehicles (UAVs).
The 640 × 512-pixel (25-µm pitch) camera weighs 120 g with the 23-mm f/1.15 lens, providing a 40° field of view. The <4.9-cu in. total volume allows it to easily fit onboard most unmanned aerial or ground vehicle systems. Currently the low-SWaP camera is installed in the nose cone of a Raven hand-launched unmanned aerial system.
The SWIR camera, sensitive from 0.7 to 1.7 µm, is installed on the Raven system with a 320 × 240-resolution long-wavelength infrared microbolometer. The camera augments the microbolometer’s thermal night imaging capabilities by 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 camera combined with the microbolometer on the same platform allows 24-h coverage from a single unmanned aerial system. This provides war fighters with new capabilities and new concept of operations while meeting the low-SWaP requirements of the modern battlefield. It also eases the physical burden on war fighters by allowing them to carry a single camera payload.
