Like a telescope, it has a curved mirror to collect the sunlight.
大多数天线被制成碟形，用以收集和反射无线电波至亚反射器，就像曲面镜将可见光聚焦于一点一样。
Most antennas are made in the shape of a dish to collect and reflect the radio waves to the sub reflector, in the same way as a curved mirror focuses visible light to one point.
凯克望远镜采集和集中光线的大型镜片和南非大望远镜类似，是由一组小镜片拼接成的曲面镜。
The massive mirrors that collect and focus light are, like SALT's mirror, an array of smaller mirrors arranged on a perfectly formed curve.
当你误把经双曲面镜反射的映像当作平台上存放的实物而用手去抓时，当然是什么也抓不到了。
If you take the reflections from the hyperbolic mirror for the objects on the desk, you will for sure make a vain attempt to grasp them.
通过误差矩阵和模具的工作特性函数反求输入控制量是加工高精度的自由曲面光学镜所面临的难题。
