镜子是一种极端的光面反光板，它反射的光线几乎与入射光线一样窄。
The most extreme type of shiny refiector—a mirror—will keep the light focused pretty much as narrowly in the refiection.
从折射定理出发，给出旋转双光楔的入射光线和出射光线之间的对应关系。
Starting from refraction theorem, the corresponding relation between incident light and outgoing light of the rotating double optical wedges is given.
为了使这项技术得以实施，通过“波前校正”，入射光线经过地球大气造成的扭曲会被移动。
In order for this technique to work, the distortions imposed on the incoming light during its passage through the Earth's atmosphere must be removed using a trick called "wavefront correction".
