The mechanism of a confocal laser scanning microscope is to irradiate an object with a laser beam emitted from a light source, scan the entire object in two directions, the X-axis and the Y-axis, and ...

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 ...

Physicists at Scotland’s Heriot-Watt University have created a 3D imaging camera system capable of resolving depth on a millimeter scale at distances of up to one kilometer. Working much like a laser ...

Matthew Shaw and William Trossell document the world with lasers. When the duo founded ScanLab Projects in 2011, they were a pair of freshly minted architecture school graduates who'd gotten their ...

A new portable device combines laser scanning technology with cameras to create precise 3D images in colour. It could be used for everything from infrastructure inspection to construction to robot ...

You may have heard: 3-D is hot. So hot in fact that now it’s found its way onto a device you’d think had zero 3-D powers: The iPhone 4 (or most recent iPod Touch). It’s via a scanning app called ...

A new set of laser tweezers offers scientists unprecedented control over objects just tens of billionths of a meter in size. The device could allow biologists to probe individual viruses and proteins ...

Once you have a 3D printer, making copies of objects like a futuristic Xerox machine is the name of the game. There are, of course, 3D scanners available for hundreds of dollars, but [Joshua] wanted ...
