Laser scanning technology for building security applications utilises the time-of-flight method, in which a sensor emits a pulse that is then reflected by a target, if present. The time required for ...

Right off the bat, we’ll say that this video showing a laser beam stopping in mid-air is nothing but a camera trick. But it’s the trick that’s the hack, and you’ve got to admit that it ...

This nearly eliminated the effects of ink bleed and revealed the ... forearm of mummified human remains under white light and laser scan exposing additional fine detail in the tattoo artwork ...

This 3D-printed confocal laser scanning microscope is a good example of an instrument for measuring really small stuff. As [Zachary Tong] points out, confocal scanning microscopy uses a clever ...

Precision Laser Scanning, LLC was founded by George Helser in 2015 to provide high speed polygon laser scanning information, experience and products to OEMs, Systems Integrators and others. George’s ...

Scanning a painting and laser cutting acrylic art on the Glowforge for a 3D effect.

The penetration depth of traditional confocal laser-scanning microscopy (LSM) systems is limited by light scattering. To avoid these limitations, multiphoton LSM uses a nonlinear fluorophore ...

Omnitron Sensors, a US startup developing tiny mirrors based on microelectromechanical systems (MEMS) technology, says it has raised more than $13 million in a series A round of venture finance.

The new laser technique allowed scientists to make the mummified individuals’ skin glow brightly in contrast with the black tattoo ink. This nearly eliminated the effects of ink bleed and ...
