Abstract

The CAS-6254 is an advanced Charge Coupled Device (CCD) imaging detector optimized for real-time, Long-Range Oblique Photographic (LORON reconnaissance applications. It features I I - μm pixels, high saturation level, variable length Time Delay and Integrate (TDI) operation, high line rate, integrated support electronics and buttable ends. A previous SPE paper described the CAS-6254 CCD detector and reported its initial test results.' Further testing of this device as incorporated into a seven-chip Focal Plane Array (F-PA) has produced additional performance data. Laboratory tests were conducted on the FPA, not only to complement previous test data, but to prove detector performance under imaging conditions using the actual external drive electronics. CCD output was measured at increasing TDI levels to test for TDI I output linearity. Photoresponse uniformity was measured and Radiometric Correction (RC) coefficients were generated by computer. The percent nonuniformity was plotted as a function of temperature for a given set of RC coefficients. Real-time, variable TDI operation was tested and demonstrated with imagery using a computer and Analog-to-Digital Converter (ADC) in a control loop. Imaging across the butted ends of two CCDis in the FPA was performed to illustrate the integrity of mechanical butting. Another significant test involved imaging a low-contrast target and signal processing the detector video to observe the detector's contribution to the process of E-0 haze penetration. The test data are presented with photographs of a video tape of actual test imagery.
