Abstract

This is a theoretical study of a partially coherent light source incorporating a stochastic, diffuser-like component and a deterministic, beam-splitter-like component. The resulting degree of spectral coherence in the far zone exhibits two peaks, whose shapes are determined by the Fourier transform of the source-plane intensity profile. Experimental realizations of this compound source are proposed. Implications for information coding are discussed.
