laser scanning
Beam measures surfaces
Laser scanning is a technology that uses laser beams to measure distances and capture detailed three-dimensional data about objects or environments.
A scanner emits pulses of light and records how they reflect back, creating precise point clouds that can be converted into digital models.
The technique is used in surveying, archaeology, manufacturing quality control, and creating digital twins of buildings: Laser scanning revealed structural damage invisible to the naked eye.
