摘要：

To observe spectral shift due to source correlation, usually some focussing optics is used and an aperture is placed in the secondary plane for violating the so called scaling law. Such an aperture produces diffraction which complicates the study of spectral shift due to correlation between the source points. Unlike all the earlier experiments, we have started from a coherent source which is made partially coherent by a beam expander and a rotating diffuser. The spectral shift observed in such an experiment and its implications are described.
