We’ve seen different kinds of anti-drone technology so far: from eagles (thankfully, that was canceled) to an aerial battering ram. And now there’s the Drone Dome laser, developed by an Israel-based company Rafael Advanced Defense Systems (or just Rafael). It uses a high power laser beam to track and take down hostile drones, even a few of them at once. Rafael shared a video to show off the technology, and it indeed seems pretty powerful.

It’s not a secret that things like lasers and lidar can kill camera sensors. You get an intense beam of light pointed towards your camera, and then the lens focuses it into an even brighter point, frying pixels. But did you know that diffused reflected laser light can also cause this to happen?

Photographer Andy Boyd knows. He had to learn the hard way after filming a laser tattoo removal which very quickly and easily fried a bunch of pixels on the sensor of his Sony A7SII in a series of rapid laser bursts.

Whether one is trying to photograph far away objects with a massive telephoto lens or using a microscope to document the tiny creatures that surround us, the rule is simple – if you can see it, you can photograph it.

It turns out, however, that objects don’t need to be visible to the lens in order for the camera to “see” them, as a research team from Scotland recently demonstrated.

A first of its kind camera is able to spot and track moving objects around corners in real time using short pulses of light from a laser beam.
