Abstract

We discuss the relation between the coherence of light from nonstationary sources in the space–time domain and the coherence of the monochromatic components of the light. For this purpose we use Loéve’s theory of harmonizable stochastic processes, particularly the spectral representation of a nonstationary stochastic process and the relation between its correlation function and the two-frequency spectral function as a measure of coherence of the monochromatic components of the source.
