Laser and Radar Let Researchers Peer Deep Inside Ancient Roman Bridges

Ancient stone bridges dot the Spanish hills. Some are still in use, and all play a part in defining the region's landscape and heritage. Now, researchers at Spain's University of Vigo can examine the inner structures of these bridges without disturbing a single stone, thanks to some incredibly powerful imaging… » 3/14/14 1:00pm 3/14/14 1:00pm

The First Full-Size Helicopter That Takes Off and Lands All By Itself

As if there were any doubts that the future of aviation doesn't involve humans at the controls, Boeing's Unmanned Little Bird is the first helicopter to take off and land autonomously, choosing a safe landing site using an on-board laser LIDAR—a combination of light and radar—scanner. » 9/18/13 5:43pm 9/18/13 5:43pm

Airborne Laser Scans Just Uncovered a City Lost for a Millenium

Forget trowels and tiny little brushes. The new must-have tool for archaeology is lasers. Just last month, researchers in the Honduran rainforest used them to find a lost city of gold, and now archaeologists in Cambodia have found a forgotten city that's even older. Welcome to Mahendraparvata, a metropolis unknown… » 6/15/13 1:30pm 6/15/13 1:30pm

Wind Turbine Laser System Detects Gusts Before They Arrive

A startup company named 'Catch the Wind' has developed a product that could increase the efficiency of wind turbines by up to ten percent. Currently, wind turbines lose one percent of their operating efficiency for every degree that the blades are out of alignment with the oncoming wind. The 'Vindicator' fiber-optic… » 11/06/08 1:30pm 11/06/08 1:30pm

Robotic Wheelchair Uses Lasers to Dock Like a Spaceship

A robotic wheelchair that loads itself into its owner's car using the same principles as a spaceship does when docking, has been developed by a team from Pennsylvania. An on-board computer uses LIDAR, or light detecting and ranging, to position the chair when it is loaded into a vehicle—exactly the same technique… » 4/30/08 12:30pm 4/30/08 12:30pm
