degree of coherence meaning in Chinese
相干度
Examples
- The basic concepts of second - order coherence theory in describing wavefields are introduced . these concepts are the cross - spectral density function and spectral degree of coherence in the space - frequency domain , and the mutual coherence function and the complex degree of coherence in the space - time domain
介绍了二阶相关理论中描述光场相干性质的基本概念，包括空间-时间域中的互相关函数、复相干度和空间-频率域中的交叉谱密度函数、光谱相干度。 - The main results of this thesis can be summarized as follows : 1 . based on the huygens - fresnel principle , we have derived the propagation expressions of the partially coherent beams passing through an annular lens optical system . the influence of the spectral degree of coherence , fresnel number and truncated parameter on the focused intensity distribution and focal shift is analyzed
主要工作包括: 1 .从惠更斯-菲涅耳原理出发,推导了部分相干光束通过环形透镜系统的传输公式,分析了空间相干度、菲涅耳数、拦截系数对系统中光束的聚焦光强和焦移的影响。
