Are you looking to learn the laser tracker basics, including capabilities, best practices, advantages, and next-generation functions? Our free metrology resource site offers fundamental knowledge related to dimensional measurement instruments, environment requirements, selecting the right tool for the job, and various inspection processes.
What is a laser tracker? A laser tracker is an inspection tool that accurately measure large objects by determining the positions of optical targets held against those objects. Laser trackers take measurements by having the technician first sets up a laser tracker on a tripod with an unobstructed view of the object to be measured. The technician removes an optical target (retroreflector) from the base of the laser tracker and carries it to the object to be measured, moving smoothly to allow the laser tracker to follow the movement of the retroreflector. It calculates the displacement from a reference position in a three-dimensional Cartesian coordinate system (XYZ axes).
Laser trackers allow for three-dimensional accurate measurement of large objects by determining the positions of optical targets held against those objects. Measurements include lengths, angles, diameters, planes, cylinders and GD&T measurements. Laser trackers have the advantage of being portable and providing a measurement range of several meters.
