Moreover, the beam is so tightly focused that equipment a mere dozen metres away from its line would struggle to detect it.

而且，信号流如此紧密集中，以至于仅仅几十米之外的设备都很难侦测到它。

The intensity peaks within a solenoid beam are found in a spiral around the line of the beam itself, while a Bessel beam's intensity rises and falls in peaks and troughs at higher distances from the beam's line.

This exploits one of the predictions of Einstein's general theory of relativity: that the path of a beam of light (which is a straight line in empty space) is bent inwards by the gravity of a massive object.
