Paper Abstract

The Advanced Imaging System is a slow scan, high precision CCD camera system designed specifically for low noise image acquisition and precise, highly flexible CCD testing and characterization. In addition, the system is designed to allow CCD mosaics to be supported with separate, programmable clock voltages and output amplifier operating points for each device. A high speed digital signal processor acts as the timing generator and allows all clock voltages and timing states to be adjusted through a set of downloadable parameters. Virtually any CCD can be operated with modest changes to the system hardware and software. In addition, the entire control program may be downloaded from the host computer at any time to facilitate radically different camera operation. The initial version of the camera system supports up to eight separate simultaneous readout channels with readout rates as high as 100 kHz at 16 bit precision and noise levels below 5 e- at 50 kHz. Control and data signals are connected to the host computer through a fiber optic interface for maximum distance and isolation. The system is a highly flexible CCD camera designed to operate individual CCDs and mosaics in slow scan systems where low noise is of primary importance.
