查询词典 spreading

When the angle radius of the diffraction spot's the first dark ring is big, the effect is relatively small. But when the angle radius is small, especially for turbulent effects being weak, the effect on the beam spreading is very distinct, and the magnitude of the beam spreading is mainly dependent on the jitter item of the scaling relations.

由此定标关系可知，当系统衍射角σ0较大时，跟踪抖动对光束扩展的影响比较小；但是当系统衍射角σ0较小时，特别是在湍流效应较弱的情况下，抖动的影响非常显著，此时光束扩展主要是由系统抖动项所决定的。
