Effects of Turbulence Aberration on the Focal Beam and Photon's Orbital Angular Momentum in the Atmospheric Optical Communication
湍流像差对大气通信会聚光束和光子轨道角动量的影响

"A convex lens causes rays to converge on a single point, the focal point."
会聚透镜使光线会聚于一点,即焦点。
3.
In this case the rays obviously do not converge.
此时，光线显然不会聚。
4.
When viewed using a bright lamp, the beams of light can be seen as spectra of colors.
在明亮的聚光灯光源下，光束会还原为光谱色彩。
5.
focused light rays can set something afire.
聚焦的光线会让东西烧起来。

However, dating under the spotlight rarely leads to long-lasting love.
但这种聚光灯下的约会难以产生持久的爱情。

This calls for the lasers to be very finely tuned and the fuel pellet to be perfectly smooth, so that the implosion is symmetrical and fusion occurs.
这需要精确调节激光，燃料球必须光滑，这样内爆才会对称，聚变才会发生。
