We examine the properties of the recently introduced degrees of coherence regarding the phase correlations of the optical field. It is seen that some of these quantities are straightforwardly related to the limits of complete dependence and complete independence of phases, which were used as the extremes of complete coherence and complete incoherence by Zernike in 1938. Certain other coherence measures are not in agreement with these limits in all situations. Our results elucidate the physical meaning of coherence in electromagnetic fields.
我们研究了最近引入的关于光场相位相关的相干度的性质。我们发现，这些量中的一些与相位完全相关和完全无关的极限直接相关，这些极限在 1938 年由泽尼克作为完全相干和完全不相干的极限来使用。某些其他相干度测度在所有情况下都与这些极限不一致。我们的结果阐明了电磁场中相干性的物理意义。
