A linear encoder can be used to significantly improve the accuracy and repeatability of stepper or servo-motor positioning stages, but even the high-end linear encoders have linearity errors. To reduce these errors, a laser interferometer measures them and uses a motion controller with the capability to store a dynamic error map.
