Advanced Imager Technology (Group 87)

The Advanced Imager Technology Group performs research and development on detector arrays, readout integrated circuits, imager devices, cameras, and sensor subsystems for the Department of Defense and scientific community. We design and fabricate imaging devices using our in-house silicon and compound semiconductor facilities and commercial foundries. In our fabrication facilities, we have the ability to create novel devices that are not limited by standard foundry processes, design rules, or device structures.

We maintain an expertise in high-performance visible, infrared (IR), and X-ray imagers for ground-, air-, and space-based surveillance, adaptive optics, astronomy, missile defense, and more. Analog focal plane arrays have been built to address special requirements; for example, we have built large-format gigapixel arrays, very high-speed imagers (100 ps exposures), and low-light-level imagers. Digital-pixel focal plane arrays have been designed and built for the collection of wide-area IR surveillance and high-dynamic-range imagery. We design and fabricate single-photon-sensitive imagers for both time-of-arrival (LADAR receiver) and passive imaging applications in the visible, near-IR and short-wave-IR wavelength ranges. We also design and build computational imagers that contain digital signal processing electronics integrated into the pixel array of an imager. 

World-class charge-coupled-device (CCD) imagers fabricated by this group have been used in a variety of high-end scientific applications; for example, focal planes were developed for the space-based NASA Chandra X-ray telescope and other preeminent astronomical observatories, and high-speed imaging applications at Los Alamos and Berkeley National Laboratories. Photon-sensitive time-of-arrival imagers have been utilized in the Airborne Ladar Imaging Research Testbed (ALIRT) LADAR sensor used to produce precise three-dimensional terrain maps for defense and humanitarian applications. Infrared digital-pixel focal plane arrays have enabled the Wide-Area Infrared System for 360° Persistent Surveillance (WISP-360) system to provide day/night persistent surveillance for base protection and security.
