Abstract

A spectral approach to the theory of partial coherence of nonstationary light [M. Bertolotti et al., Pure Appl. Opt. 6, 153 (1997)] is applied to the study of spatial coherence properties of nonstationary wave fields on propagation in free space. Three types of nonstationary light sources are considered—a point source, a spatially incoherent source, and a uniformly coherent source, the last being perfectly coherent in both space–time and space–frequency domains. An example of the diffraction pattern from a slit with nonstationary partially coherent illumination is used to illustrate the general discussion.

  15. As is shown in Refs. 5 and 6, the energy of a pulsed source is equal to the sum of intensities of the source monochromatic components—in our case given by Eq. (2.3), multiplied by the factor 2π, which constitutes a generalization of the Parceval theorem to pulsed stochastic processes of finite energy.

  21. It means also that if a thin opaque screen with a small aperture is illuminated from a point source, the spatial coherence of light will not change across the aperture, forming in this way a secondary uniformly coherent source, as is defined by Eqs. (2.1) and (2.2).
  22. Considering the far-zone wave field, it is more exact to say that the normalized spectrum, time intensity, and energy remain unchanged in certain directions of observation, changing if this direction changes, as is shown in Refs. 345678910.
