England Makes 3D Data of the Entire Country Free After Minecrafters Ask For It

Laser scanning has helped England do everything from discovering new things about Stonehenge to planning better flood infrastructure. Now, the country has made the entirety of its massive trove of scans available for free—in part because of requests from everyone from researchers to Minecraft players. »10/14/15 2:40pm10/14/15 2:40pm

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 1:00pm3/14/14 1:00pm

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 1:30pm6/15/13 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 1:30pm11/06/08 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 12:30pm4/30/08 12:30pm
