laser scanner
Light-beam data capturer
A laser scanner is a device that uses a focused beam of light to read information or capture the shape of objects.
Barcode scanners at checkout counters are common examples.
In surveying and 3D modeling, laser scanners measure distances to thousands of points per second, creating detailed digital representations of buildings, landscapes, or objects: The archaeologists used a laser scanner to map the cave system.
