We describe the anomalous behavior of the spectral degree of coherence as a function of light frequency in the vicinity of phase singularities of partially spatially coherent, polychromatic wave fields. We distinguish the discovered spectral coherence anomalies from conventional spectral anomalies realized with fully spatially coherent optical fields. We also demonstrate how the previously reported spectral anomalies can be engineered in partially spatially coherent fields.
我们描述了部分空间相干、多色波场相位奇点附近光频域光谱相干度的异常行为。我们将所发现的光谱相干异常与完全空间相干光场产生的常规光谱异常区分开来。我们还展示了如何在部分空间相干场中设计先前报道的光谱异常。
