摘要:
A method of determining presence of variations in interline spacing in a first image comprising a first plurality of parallel lines of pixels comprising: providing a second image comprising a second plurality of parallel lines; orienting the images so that the lines in the first and second pluralities are superimposed and angled with respect to each other to generate an interference image comprising a Moiré interference pattern; and using the Moiré interference pattern to determine presence of said variations.
