title: Multiple annular circular aperture: maxima and minima of the diffraction pattern.
abstract: The radii of the first three minima (zeros) and secondary maxima of the diffraction pattern produced by a circular aperture divided into alternating opaque and transparent annular zones are calculated for some numbers of these zones. The intensities in the first five secondary maxima are also given.
