Hello, everybody. I am currently designing a robot vision system. I have a choice either use a cheap CCD sensor with a fast shutter or a expensive CCD sensor with a storage area. Is anyone out there has information on electronic shutter? I don't want those that has mechanical parts. The shutter has to be pure electronics. It is like a LCD screen which turns black when polarize. Is there such a thing exist? Any help will be greatly appreciated. simpson@sunee.waterloo.edu \*==================================================================*\ "You want a signature?

I have a hunch that it's a feature of the CCD. --kyler

There may be others but all of the LCD 'shutters' I've seen turn translucent, not opaque when energized. This may be a problem with the CCD. John
