Low Smear CCD Camera for High Frame Rates

摘要

A small versatile CCD camera is described. Frame readout times from one second to milliseconds can be changed continuously or at random by a programmable clock. A very large range of light intensity is thus covered without the need for a mechanical aperture control. The camera can be reset at any time and then restarted at a different frame rate after the pause of a selected duration. Sony, Inc. ICX016AL sensor was found especially suitable for clock rates up to 50 MHz. Image smear, blooming and noise are substantially lower than in earlier interline transfer CCD sensors. Critical circuits are also described and measured data presented. 5 refs., 8 figs. (ERA citation 14:020455)
