惠更斯-菲涅耳原理 meaning in Chinese

huygens-fresnel principle

2 . according to the huygens - fresnel principle , we have derived the propagation expressions of the partially coherent beams passing through dual - focus optical systems and investigated the phenomenon of focal switches of the partially coherent
2 .从惠更斯-菲涅耳原理出发,推导了部分相干光束通过双焦聚焦透镜系统的传输公式,研究了部分相干光束聚焦的焦开关现象。
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。
