Laser line scanning is ideal for non-contact measurement applications - including inspection, cloudto-CAD comparison, rapid prototyping, reverse engineering, and 3D modeling. Laser line probes use a triangulation process to find the position of objects in space. A high performance laser diode inside the unit produces a straight laser stripe that is projected onto a surface and a camera looks at the laser stripe at a known angle to determine the location for each point on the line.
