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 ...

Structured light can significantly enhance information capacity, due to its coupling of spatial dimensions and multiple degrees of freedom. In recent years, the combination of structured light ...

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 ...

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 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 ...

Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...

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 ...

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 ...
