This paper describes a high-frame rate CCD camera capable of operating at 100 frames/s. This camera utilizes Kodak
KAI-0340, an interline transfer CCD with 640(vertical)×480(horizontal) pixels. Two output ports are used to read out
CCD data and pixel rates approaching 30 MHz.
Because of its reduced effective opacity of vertical charge transfer registers, interline transfer CCD can cause undesired
image artifacts, such as random white spots and smear generated in the registers. To increase frame rate, a kind of speed-up
structure has been incorporated inside KAI-0340, then it is vulnerable to a vertical stripe effect. The phenomena
which mentioned above may severely impair the image quality.
To solve these problems, some electronic methods of eliminating these artifacts are adopted. Special clocking mode can
dump the unwanted charge quickly, then the fast readout of the images, cleared of smear, follows immediately.
Amplifier is used to sense and correct delay mismatch between the dual phase vertical clock pulses, the transition edges
become close to coincident, so vertical stripes disappear. Results obtained with the CCD camera are shown.
