Scientists have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot. The work shows that optical knots could be used as a ...

The idea behind the ring laser gyroscope actually dates back to 1913, when a French physicist, Georges Sagnac, experimented with rays of light moving in opposite directions around a circular ...

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

If you already have a 3D printer, you already have a machine that will trace out gears, cogs, and enclosures over an XY plane. How about strapping a laser to your extruder and turning your printer ...

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

[Andreas Bastian] has been working on a device that turns an off-the-shelf laser cutter into something capable of selective laser sintering of powdered plastics into 3D objects. He’s put in a ...

By 2024, 3D laser scanner sales are expected to reach USD 1,844.5 million worldwide, driven by a 6.6% compound annual growth ...

The fourth industrial revolution is now underway with the combination of digital and physical technologies to allow production and control on demand: an industrial internet of things. A crucial ...
