  • However, this does not take into account the optics of the system which degrade image quality somewhat giving a commonly accepted resolution of 1 arcminute/cycle.

    The Register

  • So, if a normal human eye can discriminate two points separated by 1 arcminute/cycle at a distance of a foot, we should be able to discriminate two points 89 micrometers apart which would work out to about 287 pixels per inch.

    The Register

  • See, I'm just biased towards interferometers; -) ** One arcsecond is 1/60th of an arcminute, and one arcminute is 1/60th of a degree.
