Abstract
Reconnaissance systems incorporating solid-state image sensors have advantages over film- based systems in their ability to provide real-time images and transmit digital data to a remote location. In this application area array sensors have advantages over linear and TDI type sensors in eliminating the need for the aircraft to travel in a straight line as is required for 'push broom' imaging. DALSA has previously developed a single output 2048 X 2048 area array which evolved to a four output high speed image sensor suitable for airborne reconnaissance. In this paper we discuss a four output 5120 X 5120 image sensor; this sensor is a prototype for an 8 output imager suitable to replace film recording media for airborne reconnaissance. We review the performance of the existing 5120 X 5120 array and discuss the design modifications implemented on the second generation device to match reconnaissance requirements, improve performance and enhance yield.
