Notes:
High-sensitivity, low-noise, and high-frame-rate charge-coupled-devices (CCD) and camera system electronics have been developed for imaging applications in the visible and near infrared spectra. Back-illuminated CCD imagers are used in the camera system for sensitive signal detection. A fabrication technology, using a refractory process, has been developed for CCD back-illumination that has quantum efficiencies as high as 90% from 500 to 700 nm and 50% from 200 to 400 nm. The CCD imagers use multiple output ports, with single-port pixel rates up to 5 MHz, for low-noise operation at high frame rates. An electronic shutter has been integrated into the pixel structure that has switching times of approximately 50 ns and an extinction ratio value of 104 (signal detected shutter opened to shutter closed) at wavelengths below 540 nm. A flexible electronic board set, providing various operating modes, has been designed to run the CCD at high frame rates while maintaining the detection sensitivity of the imager. © 1997 American Institute of Physics.
