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 ...

Shaped quantum light is turning ordinary photons into powerful tools for the future of technology.

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

Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of applications. Pushing the limits of structured light, Harvard applied physicists in ...

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 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 ...

Photonics researchers have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light's ...

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 ...

Researchers from Wits University and Universitat Autònoma de Barcelona show how controlling the structure of photons in space and time enables tailored quantum states for next-generation communication ...
