A Method to Calibrate Angular Positioning Errors Using a Laser Tracker and a Plane Mirror

A Method to Calibrate Angular Positioning Errors Using a Laser Tracker and a Plane Mirror

We describe a method to calibrate angular positioning errors of a rotation stage using a laser tracker (LT), a plane mirror mounted on the stage, and stationary registration nests placed around the stage. Our technique involves determining the direction of the normal vector to the plane of the mirro...
