摘要：
We derive an expression for the far-zone scintillation index of electromagnetic beams that are generated by quasi-homogeneous sources. By examining different types of sources, we find conditions under which this index reaches its minimum or its maximum value, It is demonstrated that under certain circumstances two sources with different spectral densities can produce beams with identical scintillation indices.
