Just a question.
If we are using a CCD to image an object, we know that we would need to have the size of a CCD element to be half of that of the smallest object feature we required to image in order to match the Nyquist Criterion. ie we would require two CCD element to image one object feature. When we display the image, do we simply display what is capture on each CCD element?
What about if we use a photodetector(assuming a scanning system), does this mean each scan movement must be half of the smallest feature?
Thanks
