Description
Summary:An alternative method to generate J(0) Bessel beams with controlled spatial partial coherence properties is introduced. Far field diffraction from a discrete number of source points on an annular region is calculated. The average for different diffracted fields produced at several rotation angles is numerically calculated and experimentally detected. Theoretical and experimental results show that for this particular case, the J(0) Bessel beam is a limit when the number of points tends towards infinity and the associated complex degree of coherence is also a function of the number of points.
