Drones in Chile

Chilean protesters are taking police drone down with simple lasers !

Video of Chilean protesters using beams of green light to ground a police drone made the rounds on social media Wednesday. But those aren’t tractor beams or Green Lantern rings—the protesters appear to be using run-of-the-mill laser pointers to take down law enforcement-grade technology.

But how does it work ?

Chilean protesters took to the streets last month to speak out against a proposed increase in public transit fares, though the demonstrations have now turned into a countrywide expression of anger over low wages and inequality.

Video posted to Reddit late Tuesday appears to show training laser pointer pens on a police drone in an attempt to bring it to the ground. As more light beams make contact with the unmanned aerial system, or UAS, it falters, then almost escapes before a coordinated effort brings it slowly to Earth.

The laser pointers could have taken down the drone in the video in one of two ways, according to Christopher Williams, CEO of Citadel Defense Company, which is working with Customs and Border Protection to deploy anti-drone “bubbles” along the border.

If the drone was being flown manually by an operator watching through a first-person video, the bright lights might have blinded the camera, causing the operator to lose control. Alternatively, “low powered lasers have the ability to interfere with [infrared] landing sensors,” as well as the downward-facing cameras that detect obstacles below, “forcing a landing or uncontrolled drone behavior,” Williams said. Commentators on Reddit offered a third possibility: that the combined heat from all those laser pointers was enough to melt internal wiring or cause the battery to give out.

Beyond drones, laser pointers are fast becoming the tool of choice for protesters around the world. In Hong Kong, people in the streets are using laser pointers to mess with facial recognition and other surveillance technologies.

While effective for grassroots purposes, Williams said he does not believe low-powered lasers like these will become widely adopted as counter-drone measures. That said, high-powered lasers are certainly being developed to destroy or otherwise knock drones out of the air. Rather than scrambling sensors or blinding operators, the high-powered versions turn up the heat, melting a drone’s components or internal wiring or causing batteries to explode.
