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 ...

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 ...

A quirk in scientific 3D modeling has led to the discovery that laser light can — under the right circumstances — cast its own shadow. The finding challenges our current understanding of what ...

Engineers at Duke University have successfully manipulated laser beams to create intricate 3D patterns known as 'optical ...

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

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

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

Our LightFab 3D Printer consists of a high dynamic 3D Microscanner, a high precision 3-axis system for stepping, fs-laser, camera and vision system for automatic alignment, laser safety and an ...

No, for two reasons: 1.) The laser is moving and it never has constant focus at any one location (think PWM, you’re not shining at full power on any one location). 2.) The power of this unit is ...

The global 3D laser scanners market is experiencing growth due to several factors, such as technological advancements in manufacturing sectors paired with a rise in the popularity of 3D laser ...

“The technology uses less expensive light sources as simple as a laser pointer ... and health care. Femtosecond laser two-photon polymerization is widely used for 3D nanostructure fabrication.
