A recently formulated theory of partial coherence in the space-frequency domain is used to determine the mode structure of an important class of partially coherent sources and of the radiation fields generated by them. The effective number of modes is found to depend in a fundamental way on the ratio of the coherence length to the effective size of the source. The contribution of the effective modes to the far-field intensity is also analyzed.

  6. Actually a third case is possible: Eq. (2.1) may represent the cross-spectral density of the field across a primary source.
  7. To keep the notation as simple as possible, we have suppressed in Eqs. (2.7) and (2.8), and also in some subsequent equations, the explicit dependence of some of the quantities on the frequency ω.

  11. Our argument leading from Eq. (4.1) to Eq. (4.5) is obviously appropriate when the source is finite. When the source is infinite, a more careful analysis is required, but it seems intuitively obvious that, in view of the exponential decrease of the mode functions øn (x′) with increasing |x′|, formula (4.5) will hold in the present case also.
