这种类型的望远镜称为反射望远镜，比折射望远镜更具有优势，后者需要用到两个透镜，而且会受到光学畸变效应的影响。
Such telescopes are called reflectors, and they offer major advantages over refractors, which use two lenses and suffer from optical distortion effects.
利用这种效应可以实现微波信号的光学处理，可以作为研究微波光子学一种新的途径。
The microwave signal can be processed in optical-domain by the MO Bragg diffraction effect, which can be used as a new approach for studying microwave photonics.
我们分析发现造成这种现象的物理原因是多模干涉区的自成像效应，这种多模干涉在光子晶体光学集成电路中具有重大的潜在应用价值。
We analyse the physical origins of this performance is the self-imaging principle in the multi-mode region, this kind of multi-mode interference may find potential application in PC optical circuits.
