Common-Path Method for Laser Tracker Ranging Calibration Volume 9, Issue 1 Chris Blackburn, Daniel Sawyer, Craig Shakarji In this article, we present an alternative to the back-to-back method of testing laser tracker ranging systems. Our approach uses a common air path for both the measurement and reference laser beams. This technique allows for more accurate determination of...

The Uncertainty of Coordinate Metrology as a Function of Sampling Strategy Volume 9, Issue 1 Ahmad Barari, Farzaneh Kaji The main objective in all metrology processes is to limit uncertainty. The objective of coordinate metrology processes is not any different. A coordinate metrology process is successful only if it reduces the level of uncertainty in geometric and...
