Homework Help: CCD accuracy

  1. Sep 23, 2005 #1
    The following question appeared on one of my exam papers.

    A CCD of pixel density 10Mpixel (1cm^-2) is used to image a component of length 10cm.
    Show how this does or does not meet the required accuracies of +/- 0.025mm.

    A similar question was asked in a previous exam where the component's length was 10cm but a width of 1cm was also specified.

    I would like to know whether or not both length and width are required in order to determine a solution.

    I was of the impression that both dimensions would be needed but my lecturer disagrees.

    Can anyone clarify the situation?
