Abstract

In this paper, the reason of ordinary CCD's low frame rate was analyzed, and a novel high-speed image sensing technique with adjustable frame rate based on an ordinary CCD was proposed. The principle of the image sensor was analyzed. When the maximum frequency and channel bandwidth were fixed, a custom high speed camera was designed by using the ordinary CCD under the control of the special driving circuit. The frame rate of the ordinary CCD has been enhanced by reducing the number of pixels of every frame, therefore the ordinary of CCD can be used as the high frame rate image sensor with small pixels. The multi-output high speed image sensor with small pixels by using this technique can overcome the deficiencies of low resolution, low accuracy, and high price. The light intensity varying with time was measured by using the image sensor. The frame rate was less than 1600frame/second, and the size of every frame and the frame rate was adjustable. The correlation coefficient between the measurement result and the normal value was higher than 0.95, and the relative error was lower than 0.52%. The feasibility of the high-speed image sensing technique was proved by the experiments.
