I am carrying out some research on CCDs for a h/w design project that I have coming up that would include a 2D bar-code scanner module. I know that there are ready made modules available and thus there is no need to design one ourselves, still I would like to know a little more about barcode scanners. To that effect I have a few questions
Are the CCDs used in bar-code scanners, especially for 2D scanners, similar to those used in cameras? If not, what is the exact difference?
A pointer to specific brands and/or manufacturers would also be nice.
