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 ...

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 ...

Physicists have made a groundbreaking discovery that challenges the traditional understanding of light by demonstrating that ...

"Laser light casting a shadow was previously thought impossible since light usually passes through other light without interacting," study co-author Raphael Abrahao, a physicist at Brookhaven National ...

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 ...

Photoshop CS6 Extended tutorial showing how to cast realistic shadows from any object including those with irregular bases.

Researchers from MIT and Meta have developed a computer vision technique that could enable an autonomous vehicle to perceive their wider surroundings – including right through nearby vehicles. The ...

Rakesh Malik on the importance of embracing the dark side and using shadows to their full extent. In both photography and cinematography, the focus tends to be on exposure. That should come as no ...

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 ...
