NASA team advances next-generation 3D-imaging lidar

(Phys.org) —Building, fixing, and refueling space-based assets or rendezvousing with a comet or asteroid will require a robotic vehicle and a super-precise, high-resolution 3-D imaging lidar that will generate real-time ...

iPhone 5S fingerprint scanning: Thumbs up or down?

Technology to acquire and use biometric data such as fingerprints has been around for several decades and has made its way from forensic investigation to laptop computers – and now, with this week's introduction of iPhone ...

Authentic brain waves improve driver security

One-time entry authentication methods, such as passwords, iris scanners and fingerprint recognition are fine for simple entry whether to a protected building or a private web page. But, a continuous biometric system is needed ...

Giant 3-D printed bugs shed light on insect anatomy

Minute insects, from the Australian National Insect Collection, have been super sized by up to forty times using a novel 3D scanning system and printed using a state of the art 3D printer.

Physicists help design, build cargo X-ray scanners

(Phys.org) —Two SLAC physicists with decades of particle accelerator experience helped a Silicon Valley company design and build X-ray devices that scan cargo containers for nuclear materials and other hazards. A version ...

Building quantum states with individual silicon atoms

(Phys.org) —By introducing individual silicon atom 'defects' using a scanning tunnelling microscope, scientists at the London Centre for Nanotechnology have coupled single atoms to form quantum states.

New freeform standards to support scanning CMMs

The National Physical Laboratory (NPL), the UK's National Measurement Institute, has developed a new range of three dimensional standards for verifying freeform coordinate measurement machines (CMMs). The standard allows ...
