Linear Laser Performance: How Distance, Environment, and Setup Affect a Laser Tracker’s Linear Accuracy

by Mateusz Turolski and Lukasz Turolski, ECM Global

Calibration of laser trackers using precision rails and a reference interferometer (one with no angular encoders) is the most precise way of evaluating linear performance, yet only a handful of institutions and companies use such equipment. In addition, little research has been conducted examining the added benefits and capabilities of precision rails when evaluating the linear performance of laser trackers.1 A wide array of calibration procedures exist, many of which do an adequate job of testing tracker performance.
