Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...

The approach uses lasers and holograms to detect misalignments as small as 0.017 nanometers. Researchers at the University of ...

Combining laser engraving with 3D printing creates unique, customizable items quickly and inexpensively. Creative projects ...

Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or ...

Semiconductor chips have traditionally been manufactured in two dimensions. But as devices become more powerful and compact, ...

you could get that mesh point to form complex shapes in 3D on demand. For the past few years, researchers have essentially been doing this with light. By overlapping several laser beams with ...

NASA laser data reveals how climate change is reducing tropical forest canopy height, with dry seasons driving major changes.

Creativity requires instant response and record. In the 3D industry, this is especially true. Portable 3D scanner, as one of the most important tools in 3D projects, bridges your brain world to the ...
