In the article, the optical coupling between the optical fibre and detector is stressed and the coupling scheme of a combined lens is designed and calculated concretely.

文中着重论述了光纤与探测器间的光耦合问题，并就一组合透镜耦合方案作了具体设计计算。

In the light of the soft-ness of fibre bunch, the detector and refrigerator module can be placed at a distance from universal hold-er by optical fibre coupling technique.

利用纤维光束的柔软性，应用光纤耦合技术，可以让探测器和致冷器组件放在离万向支架一定距离上。
