Laser Tracker

A high-precision laser measurement instrument used to accurately determine the three-dimensional position of objects and components.

Definition

A Laser Tracker is a portable coordinate measurement instrument that uses laser interferometry or absolute distance measurement to precisely determine the three-dimensional location of a reflective target. Laser Trackers are commonly used for equipment alignment, dimensional inspection, manufacturing verification, plant construction and precision metrology where measurement accuracies of fractions of a millimeter are required.

Why It Matters

Laser Trackers provide extremely accurate dimensional measurements for alignment, inspection and precision engineering applications.

In Practice

Unlike terrestrial laser scanners that capture millions of points across large areas, Laser Trackers measure discrete target locations with significantly higher positional accuracy.

Common Misuse

Laser Trackers measure selected target points with very high accuracy, whereas Laser Scanning captures dense point clouds representing complete surfaces and facilities.
