Fundamentals

1Overview

What is alaser tracker? Alaser trackeris an inspection tool that accurately measures large objects by determining the positions of optical targets held against those objects.Laser trackerstake measurements by having the technician first sets up alaser trackeron a tripod with an unobstructed view of the object to be measured. The technician removes an optical target, known as a retroreflector (SMR), from the base of thelaser trackerand carries it to the object to be measured, moving smoothly to allow thelaser trackerto follow the movement of the retroreflector. It calculates the displacement from a reference position in a 3D Cartesian coordinate system (XYZ axes).

2Capabilities and Advantages

Laser trackersallow for accurate 3D measurement of large objects by determining the positions of optical targets held against those objects, giving users an advantage over single dimension or 2D measurement instruments such as calipers, micrometers, and large optical comparators.Laser trackershave the advantage of being portable and providing a measurement range of several meters. Being wireless tools, they also give flexiblity beyond part inspection, enabling machine tool measurement, alignment checks and even calibration of motorized objects such as robotic arms.

3Core Technology and Advancements
