In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...

You can’t understand light without also knowing darkness. It’s like you can’t understand true happiness unless you also experience sadness. The best design comes when there’s a balance between light ...

A new technique can model an entire 3D scene, including areas hidden from view, from just one camera image. The method relies on image shadows, which provide information about the geometry and ...

Students learn that shadows are created when objects block light from shining on the ground. Students are asked to trace the shadow of a stick five times throughout the day. ----- Transcript ...

Every year at Adobe Max, Adobe shows off what it calls “Sneaks,” R&D projects that might — or might not — find their way into commercial products someday. This year is no exception, and lucky for us, ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...
