CCD与光纤阵列之间采用反射镜和透镜耦合方式，使CCD避开中子源直接辐照。
To avoid direct radiation from neutrons, the CCD is coupled to the array by a mirror and lens optics.
LD与光纤的耦合，按照LD与光纤之间是否存在光学元件，耦合方式可分为两种，即直接耦合与间接耦合。
The methods of coupling between LD and optical fiber can be divided into direct and indirect coupling according to whether optical devices exist between them.
以节点自由度耦合的方式，给自由度耦合节点以强制位移，用直接求出自由度耦合节点约束反力的方法来求抽筒力。
The reaction force, that is extracting force, is solved directly by coupling DOFS of nodes and loading the DOFS nodes displacement.
最后引入了指向误差分析，比较了这两种耦合方式的优劣，最终将放大器定为直接耦合抽运方式。
From the error analysis of LDA pointing, it is found out that the amplifier without micro-lens is more preferable.
