Is there anyone who knows camera sensor (either CCD or CMOS) that could be succesfully used for fast applications (2 or 3 meters/sec) keeping a good focus also for 0,5 meters?

Meters/second doesn't provide a meaningful measure of "fast", in this context.
For a camera, the definition of "fast" is in frames/second, and possibly in shutter opening time per frame. The relation between a "frame" and a "meter" is entirely up to the optics and mechanical setup. E.g. looking at an object moving at 2 m/s using a 5 cm field-of-view would require at least
(2 m/s) / (0.05 m/frame) = 40 frame/s
which might well be too much for most off-the-shelf cameras. Doing the same thing for a FOV of 10 meters away would drop that requirement to 1 frame every 5 seconds, which is trivial.
Exposition time controls how much motion blur you get looking at a fast moving object. Increasing the illumination will typically allow to reduce it quite a lot.
