Machine Positioning Uncertainty with Laser Interferometer Feedback

The purpose of this discussion is to explain the major contributors to machine positioning uncertainty in systems with laser interferometer feedback near the work point. We will use an example to quantify these uncertainties in a real implementation of a laser-feedback-driven machine. Laser interferometers are used as a measurement reference for machine correction and accuracy…
