<p>An improved CCD imaging array system (10) is disclosed which is capable of operating at 10,000 frames-per-second. The imager consists of an array (12) of 512 x 512 pixels having 16 serial output channels (40) which provides a composite output data rate up to 250 Megasamples/second. The serial output registers (40) are constructed from peristaltic CCDs, each having a GaAs FET output circuit (42) bump-mounted to the silicon substrate. A four-layer pinned photodiode (100) is utilized as the photodetector, and each photodiode has its own antiblooming drain (130). The antiblooming gates (132) double as an optical shuttering device. Sample-and-hold output circuitry is also provided.</p> |
