A Procedure to Determine the Spatial Coherence of a Wave Field
It is shown that the first-order correlation function connected with a scalar wave field, can be determined from a set of intensity distributions in the image plane, generated by different settings of the defocusing and the moment of axial astigmatism. Estimates of the error with which the coherence...

| Zusammenfassung: | It is shown that the first-order correlation function connected with a scalar wave field, can be determined from a set of intensity distributions in the image plane, generated by different settings of the defocusing and the moment of axial astigmatism. Estimates of the error with which the coherence function can be determined are derived. |
