Abstract
ITT Geospatial Systems has space-qualified a visible band interline Charge Coupled Device (CCD) image sensor with 18 million pixels developed using commercial technology. The sensor is comprised of an 4320 (H) x 4144 (V) array of 8 micron square pixels. With multiple analog outputs each operating at 20 MHz the sensor will support 30 frames per second continuous video capture. The pixel incorporates a pinned photodiode, vertical overflow drain and microlens to achieve low dark current, lag-free imaging with highspeed global electronic shutter at high quantum efficiency (QE). The vertical and horizontal CCD's are true two-phase designs which support an integrate-while-read operation. The sensor chip is mounted on an Aluminum Nitride co-fired ceramic package optimized for electrical signal integrity, thermal and optical stability. The architecture supports quadrant redundancy. The complete assembly has been space-qualified to a Technology Readiness Level (TRL) of 6 with Total Ionization Dose (TID) radiation testing at 25 Krad. The sensor exceeds 12-bit of dynamic range and 31% QE with 5 W of total power. The nonlinearity is measured to be 1.0% while the global non-uniformity is less than 2%. The low defect density of the CCD sensor allows high resolution video imaging in a space environment.
