Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a ...

After futzing around with a cheap pico projector, a webcam and a little bit of software, [Jas Strong] built herself a 3d scanner. In spite of the dozens of Kinect-based scanner projects, we’ve seen ...

In a recent article, I looked at the demise of Lytro, maker of the first consumer “light field” camera, and what it meant for the future of this technology in mobile devices. As intriguing as some of ...

Researchers from the School of Physics at Wits University, working with collaborators from the Universitat Autònoma de Barcelona, have demonstrated how quantum light can be engineered in space and ...

Extension of laser beam structures promises new laser applications. Exploration of how beam structures change during nonlinear frequency conversion processes has drawn increasing interest in recent ...

Structured light waves with spiral phase fronts carry orbital angular momentum (OAM), attributed to the rotational motion of photons. Recently, scientists have been using light waves with OAM, and ...

Scientists used a new invariant property of vectorial light to encode information. This quantity, which the team call 'vectorness', scales from 0 to 1 and remains unchanged when passing through a ...

The speed of light in a vacuum is 299,792,458 m s –1, right? Not necessarily, according to a team of physicists in the UK, which has found that the speed of an individual photon decreases by a tiny ...

What are Blue Light 3D Scanners? Structured light 3D scanners, typically mounted on a camera stand, robot, or tripod, function as point-and-shoot cameras and need little or no programming with minimal ...

Structured Illumination Microscopy (SIM) is a tool which breaks the diffraction resolution barrier to provide resolutions of up to 20nm. The resolution of conventional microscopes is limited by the ...
