Abstract
Fraunhofer diffraction patterns produced by a circular aperture suffering from spherical aberration and illuminated by partially coherent light are presented. Improvement in the images has also been shown when an appropriate amplitude filter is used. Tolerances for the value of the coefficient of aberration based on the Strehl criterion have been calculated for various values of correlation intervals contained in the aperture. Two forms of mutual coherence function and four values of aberration coefficient have been assumed.Keywords
