1280x1024 InGaAs Camera for Visible and Short-wave Infrared Imaging

We will design, develop, and deliver a 1280x1024 pixel indium gallium arsenide (InGaAs) focal plane array (FPA) and camera for visible and short wavelength infrared (SWIR) imaging. A 1280x1024 substrate-removed InGaAs focal plane array with high quantum efficiency from 0.4 µm to 1.7 mm will be developed for use in this camera. The camera will thus be usable for visible imaging, low light SWIR imaging and for the imaging of the Chemical Oxygen Iodine Laser emitting at 1.315 microns, utilized in ballistic missile defense (BMD) applications. In addition, the use of the InP/InGaAs material system provides inherent radiation hardness for space-based applications. This program will leverage technology developed for our commercial 320x240 visible/SWIR camera and our 640x512 SWIR camera. During Phase I, we will develop a 640x512 substrate removed InGaAs array that will mate with our current read-out integrated circuit (ROIC). This will be integrated into a camera and delivered at the end of Phase I. During Phase II, we will develop a 1280x1040 element ROIC and photodiode array for the high resolution combined visible SWIR camera to be delivered at the end of Phase II.
