普通光源的时空相干度分析

Spatial-temporal Coherence of General Light Source

在分析光源的非单色性和宽度对干涉条纹可见度影响的基础上，推导出普通光源的时空相干度计算公式，并定义了相干线域、相干面域和相干体域等概念．

Based on the effect of the light source＇s nonmonochromatic and width on the visibility of interference fringes, the formula of spatial - temporal coherence of general light source was deduced and the concepts, such as coherent line segment, coherent curved surface and coherence space, were defined.
