China is projecting laser light shows across highways to fight drowsy driving. Does it work?
On a handful of long, isolated expressways in China, drivers cruising through pitch-dark stretches are suddenly engulfed in ...
LK Metrology has announced the release of its L100NX laser scanner for use on coordinate measuring machines. Unlike its red light predecessor, the L100, the new scanner uses 450-nanometer blue light, ...
Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...
