LiDAR, or Light Detection and Ranging, works by measuring the time it takes for a laser pulse to travel to an object and back. This time-of-flight measurement reveals the distance, and by scanning ...

Laser micrometers are capable of measuring outside diameter for mechanical engineering and machining purposes. Within the micrometer is a transmitting unit responsible for emitting a laser beam that ...

If you're tired of using a boring ol' remote for controlling your devices, you might like the CenWatch. It's a smartwatch that scans the underside of your hand, allowing you to make multiple commands ...

This 3D-printed confocal laser scanning microscope is a good example of an instrument for measuring really small stuff. As [Zachary Tong] points out, confocal scanning microscopy uses a clever ...

The main mechanical tools in a hacker ... if you were lucky. Laser cutters are still a rare tool to find in a personal shop, but today’s hackers increasingly have access to 3D printers.

Advanced sensing features are coming to wearables beginning in 2025 and Penn State’s device, made with laser-modified ...
