The coherence theory predicts that the correlation in the fluctuations of a source distribution can cause frequency shifts in the spectrum of the emitted radiation, even when the source is at rest relative to the observer. Recently, we have measured the angular spectrum redistribution, or frequency shifts from 1D and 2D rough surfaces with laser sources, and further verified the spectral and spatial coherent interference effect of a finite-band source.
